For the electronic device 1000, since the Wi-Fi frequency band, the MB frequency band, and the HB frequency band are integrated in one antenna assembly 100 for transmission and reception, from the perspective of the feeding system, only one feeding system needs to be set. Compared with the Wi-Fi frequency band Setting different feed systems and mobile communication frequency bands respectively reduces the number of feed systems that need to be set, thereby reducing the space occupied by the circuit board 500 carrying the feed systems.

In general technology, some areas of the electronic device 1000 are not equipped with circuit boards, such as the area where the battery 600 is installed.

The space of 500 improves the space utilization rate of the antenna assembly 100 in the electronic device 1000 .

This application takes the electronic device 1000 as a mobile phone as an example for illustration. With the popularity of mobile communication network signals and Wi-Fi signals, more and more people like to surf the Internet when the mobile communication network signals and Wi-Fi signals are fully turned on. When there is a Wi-Fi network, the electronic device 1000 can automatically connect to a Wi-Fi signal, and when there is no Wi-Fi network, the electronic device 1000 can automatically switch to a mobile communication network signal. However, users often block the antenna on the mobile phone when holding and using the mobile phone (for example, playing games or watching videos on the horizontal screen), resulting in poor signal from the antenna and poor user experience.

The antenna assembly 100 provided by this application sets the MB frequency band and the HB frequency band on two radiators (the main radiator 12 and the first sub-radiator 11) respectively, and neither the first sub-radiator 11 nor the main radiator 12 When blocked, the antenna assembly 100 can support MB frequency band, HB frequency band and Wi-Fi frequency band. When the main radiator 12 is blocked and the first sub-radiator 11 is not blocked, the antenna assembly 100 can still support the Wi-Fi frequency band and the HB frequency band in the mobile communication signal. Dual support for communication signals, without only supporting Wi-Fi signals due to the main radiator 12 being blocked, and if there is no coverage of Wi-Fi signals, this will lead to extremely poor signals of the electronic device 1000, which will affect the use of users A question of experience. In other words, the antenna assembly 100 of the present application sets the MB frequency band and the HB frequency band on two radiators respectively, which can increase the usage scenarios of the antenna assembly 100 supporting both Wi-Fi signals and mobile communication signals, and improve the user's online experience.

By setting the MB frequency band, N78 frequency band, N79 frequency band, and Wi-Fi frequency band fed by the first feeding system 30 to feed into the first radiator 10, the MB frequency band fed in is designed to resonate at the matching point B to the first coupling end 121 Between, and the fed-in N78 frequency band, etc. resonate on the bracket radiator 17, so that the first antenna module 100a supports the MB frequency band and the N78 frequency band through the first feeding system 30, the main radiator 12, and the bracket radiator 17 The first antenna module 100a can support multiple frequency bands, and the space occupied by the first antenna module 100a in the electronic device 100 is relatively small.

Please refer to FIG. 4 , the first radiator 10 further includes a sub-radiator (referred to as the first sub-radiator 11 in this application). The structure of the first sub-radiator 11 in this embodiment is the same as that of the first sub-radiator 11 in the first antenna module 100a of the first type. Specifically, the first sub-radiator 11 has a ground terminal (referred to as the first ground terminal 111 in this application) and a second coupling terminal 112 . The first coupling gap 13 is between the second coupling end 112 and the first coupling end 121 . The first ground terminal 111 is grounded. The HB frequency band at least resonates with the first sub-radiator 11 . The Wi-Fi frequency band resonates with the first sub-radiator 11 or resonates with the first sub-radiator 11 and the main radiator 12 .

By resonating the fed-in MB frequency band at the matching point B of the main radiator 12 to the first coupling end 121, and resonating the fed-in HB frequency band in the first sub-radiator 11, and resonating the fed-in Wi-Fi frequency band Based on the first sub-radiator 11 or resonant on the first sub-radiator 11 and the main radiator 12, in this way, the antenna assembly 100 realizes supporting Wi- The Fi frequency band, the MB frequency band, and the HB frequency band, wherein the MB frequency band and the HB frequency band are different frequency bands of mobile communication signals, and the antenna assembly 100 increases the supported frequency bands, and also makes the space occupied by the antenna assembly 100 in the electronic device 1000 relatively small.

The following describes an example of frequency band support with reference to the first antenna module 100 a shown in FIG. 4 . Certainly, the following implementation manners can also be combined into the first antenna module 100a shown in FIG. 3 and the first antenna module 100a shown in FIG. 5 . Referring to FIG. 6 , taking the first antenna module 100 a installed on an electronic device 1000 as an example, the first radiator 10 further includes a second sub-radiator 15 . The main radiator 12 is located between the first sub-radiator 11 and the second sub-radiator 15 . The second sub-radiator 15 has a third coupling end 123 and a second grounding end 124 , wherein there is a second coupling gap 16 between the third coupling end 123 and the free end 122 of the main radiator 12 . The main radiator 12 is coupled to the second sub-radiator 15 through the second coupling slot 16 . The second coupling slot 16 is a gap between the main radiator 12 and the second sub-radiator 15, for example, the width of the second coupling slot 16 may be 0.5-2mm, but not limited thereto size. The main radiator 12 and the second sub-radiator 15 can be regarded as two parts formed by separating the main radiator 12 by the second coupling slot 16 .

Optionally, please refer to FIG. 7 , the Wi-Fi frequency band includes a Wi-Fi 2.4G frequency band. The working modes of the HB frequency band and the Wi-Fi 2.4G frequency band include resonating between the second coupling end 112 and the first grounding end 111 . In other words, the current generated by the first feeding system 30 at least resonates between the second coupling end 112 and the first grounding end 111 to excite the resonance of the HB frequency band and the Wi-Fi 2.4G frequency band model.

Wherein, the resonance mode is characterized by the fact that the antenna assembly 100 has a higher efficiency of transmitting and receiving electromagnetic waves at and near the center frequency of the supported frequency band. The center frequency and its vicinity form a frequency band supported or covered by the resonance mode.

Please refer to FIG. 7 , the current corresponding to the resonance mode generated by the radio frequency signals of the HB frequency band and the Wi-Fi 2.4G frequency band fed by the first feeding system 30 is mainly distributed in the second coupling end 112 and the first ground terminal 111. It can also be expressed as that the current density generated by the HB frequency band and the Wi-Fi 2.4G frequency band fed by the first feeding system 30 is mainly distributed on the first radiator 10 . Between the second coupling end 112 and the first grounding end 111. It should be noted that, in the current corresponding to the resonant mode generated by the first radiator 10, the radio frequency signals of the HB frequency band and the Wi-Fi2.4G frequency band fed by the first feeding system 30 are relatively small. A strong current is distributed between the second coupled terminal 112 and the first ground terminal 111, which does not rule out that due to the coupling effect between the first sub-radiator 11 and the main radiator 12, the first A small amount of current generated by the RF signals of the HB frequency band and the Wi-Fi 2.4G frequency band fed by the feed system 30 is distributed to the main radiator 12 . The present application does not limit the direction of the resonant current. As shown by the dashed arrows in FIG. 4 , the resonant current generated by the radio frequency signals of the HB frequency band and the Wi-Fi 2.4G frequency band flows from the first coupling slot 13 to the first ground terminal 111 .

Wherein, the HB frequency band and the Wi-Fi 2.4G frequency band are similar, and by designing the effective electrical length of the first sub-radiator 11, it can be satisfied at the same time by setting the HB frequency band and the Wi-Fi 2.4G frequency band to resonate at The first sub-radiator 11 enables the first sub-radiator 11 to simultaneously support the HB frequency band and the Wi-Fi 2.4G frequency band, thereby improving the utilization rate of the first sub-radiator 11 . When the first sub-radiator 11 can support the HB frequency band and the Wi-Fi 2.4G frequency band at the same time, compared with the HB frequency band and the Wi-Fi 2.4G frequency band respectively composed of two different radiator branches (or two different antenna modules) radiation can greatly reduce the space occupied by antennas supporting the HB frequency band and the Wi-Fi 2.4G frequency band in the electronic device 1000 .

Further, the working modes of the HB frequency band and the Wi-Fi 2.4G frequency band include a 1/4 wavelength mode resonant between the second coupling end 112 and the first grounding end 111 . In other words, the resonance mode generated by the radio frequency signals of the HB frequency band and the Wi-Fi 2.4G frequency band fed by the first feeding system 30 is that the resonance current mainly works from the first ground terminal 111 to the 1/4 wavelength mode of the second coupled end 112 .

From an easy-to-understand perspective, the 1/4 wavelength mode can be understood as the effective electrical length from the first ground end 111 to the second coupled end 112 is about the medium wavelength corresponding to the center frequency of the resonant mode (in the medium 1/4 times of the wavelength), this description is an easy-to-understand interpretation of the term, but it cannot be used as a limitation on the length from the first ground end 111 to the second coupling end 112 .

The effective electrical length of the first sub-radiator 11 is designed so that the effective electrical length of the first sub-radiator 11 corresponds to 1/4 of the medium wavelength of the HB frequency band. Wherein, the "corresponding" can be understood as the effective electrical length of the first sub-radiator 11 is about 1/4 of the medium wavelength of the HB frequency band. Correspondingly, the effective electrical length of the first sub-radiator 11 is about 1/4 of the medium wavelength of the Wi-Fi 2.4G frequency band. Wherein, the 1/4 wavelength mode may also be referred to as a base state, and the base state has higher antenna efficiency, thereby improving the transceiving efficiency for the HB frequency band and the Wi-Fi 2.4G frequency band.

It should be noted that the effective electrical length of the first sub-radiator 11 described in this application is about a certain medium wavelength of a certain frequency band, and the physical length of the first sub-radiator 11 is not limited to the medium wavelength of this frequency band. . Because some tuning devices can be electrically connected to the first sub-radiator 11 to tune the effective electrical length of the first sub-radiator 11, for example, by setting inductance and capacitance to increase or decrease the effective length of the first sub-radiator 11 electrical length.

It can be understood that the signal type of the HB frequency band mentioned in this application may be a 4G mobile communication signal or a 5G mobile communication signal. In other words, the first power feeding system 30 can load 4G mobile communication signals and 5G mobile communication signals at the same time, that is, realize the double connection (LTE NR Double Connect, ENDC) between the 4G radio access network and 5G-NR, and can also load 4G mobile communication signals separately. Communication signals, or separately load 5G mobile communication signals.

It can also be expressed as, the current density generated by the RF signal in the MB frequency band fed by the first feeding system 30 on the first radiator 10 is mainly distributed from the matching point B to the first Between the coupled ends 121 and between the first coupled end 121 and the free end 122 . It should be noted that, in the current corresponding to the resonant mode generated by the first radiator 10 of the RF signal in the MB frequency band fed by the first feeding system 30, the stronger current is distributed at the matching point Between B and the first coupled end 121 and between the first coupled end 121 and the free end 122, it is not excluded that due to the coupling effect between the first sub-radiator 11 and the main radiator 12 A small amount of current generated by excitation of the RF signal in the MB frequency band fed by the first feeding system 30 is distributed to the first sub-radiator 11 . The present application does not limit the direction of the resonant current. As shown by the dotted arrow in Figure 8, the resonance current generated by the RF signal in the MB frequency band flows from the first coupling slot 13 to the matching point B, and then flows from the matching point B to the second coupling slot 13. Gap16.

Specifically, the working mode of the MB frequency band includes a 1/4 wavelength mode that resonates between the matching point B and the first coupled end 121 and a mode that resonates between the first coupled end 121 and the free end 122. between 1/2 wavelength modes. In other words, the resonant mode generated by the RF signal in the MB frequency band fed by the first feeding system 30 is 1/4 of the resonant current mainly working between the matching point B and the first coupling end 121 a wavelength mode and a 1/2 wavelength mode between the first coupling end 121 and the free end 122 .

Specifically, by designing the position of the matching point B, the effective electrical length of the main radiator 12 between the matching point B and the first coupling end 121 is about 1/4 of the medium of the MB frequency band wavelength, so that the current excites the 1/4 wavelength mode of the MB frequency band on the main radiator 12 between the matching point B and the first coupling end 121 . In addition, the length of the main radiator 12 between the first coupled end 121 and the free end 122 is also designed so that the main radiator 12 between the first coupled end 121 and the free end 122 The length is about 1/2 medium wavelength of the MB frequency band, so that the current can excite the 1/2 wavelength mode of the MB frequency band on the main radiator 12 between the first coupled end 121 and the free end 122 . Wherein, the current intensity corresponding to the 1/4 wavelength mode is greater than the current intensity corresponding to the 1/2 wavelength mode. The intensity of the resonant current flowing from the first coupling slot 13 to the matching point B is greater than the current intensity flowing from the matching point B to the second coupling slot 16 . In other words, the 1/4 wavelength mode is dominant among the 1/4 wavelength mode and the 1/2 wavelength mode.

Above, by designing the effective electrical length of the main radiator 12 and the position of the matching point B, the main radiator 12 supports the two resonant modes of the MB frequency band, so that the main radiator 12 supports the MB frequency band, and increases the The bandwidth of the MB band mentioned above.

When the user watches videos or plays games with the horizontal screen, the user's hands are not easy to hold the main radiator 12 between the first matching point B and the first coupling end 121, thereby ensuring the strong radiation of the MB frequency band 1 The /4 wavelength mode will not be affected, which provides a good guarantee for the antenna signal when the user holds the electronic device 1000 horizontally. The MB frequency band, the HB frequency band, and the Wi-Fi 2.4G frequency band enable the user to connect to both mobile communication signals and Wi-Fi signals when holding the electronic device 1000 in a horizontal screen, so that users with Wi-Fi Switching is performed in a scenario of -Fi coverage or a scenario of no Wi-Fi coverage; in addition, the mobile communication signal can be connected to the MB frequency band and the HB frequency band, and the MB frequency band and the HB frequency band have relatively large bandwidths, In order for the antenna assembly 100 to be connected to base stations supporting mobile communication signals of different frequency bands, the electronic device 1000 can receive mobile communication signals in many places.

When the user holds the electronic device 1000, the user's fingers will not touch the radiator 17 of the bracket, which greatly reduces the shielding of the N78 frequency band transmitted and received by the radiator 17 of the bracket. The N78 frequency band can also transmit and receive smoothly in the horizontal screen holding mode, so that the user can avoid problems such as freezing when playing games in the horizontal screen mode, and improve the user experience of using the electronic device 1000 in the horizontal screen.

Since the bracket radiator 17 is not arranged on the conductive frame 310 of the electronic device 1000, the form of the conductive first radiator 10 on the bracket radiator 17 is not limited, including but not limited to straight lines, curved lines, bent lines, and arc extensions. The first radiator 10 satisfies the support for the N78 frequency band and N79 frequency band (or Wi-Fi 5G frequency band), and at the same time satisfies the need to occupy a small space. Due to the various forms of the bracket radiator 17, the effective electrical length of the bracket radiator 17 can be flexibly designed in a limited space, and the wavelength modes of the N78 frequency band and N79 frequency band (or Wi-Fi 5G frequency band) can be adjusted according to actual needs. specific design.

Since the bracket radiator 17 will not be touched by the user's hand, the N78 frequency band and N79 frequency band (or Wi-Fi 5G frequency band) have better transceiving efficiency even when the horizontal screen is held, thereby improving the electronic device 1000.

In this way, the same conductive middle frame can be used in different electronic products, which improves the compatibility of the conductive middle frame, reduces the need to open molds for various conductive middle frames, and saves costs.

When designing the first antenna module 100a of the first feeding method and the first antenna module 100a of the second feeding method, different circuit boards (PCBs) can be configured on the same conductive middle frame, The matching circuit 20, the first feeding system 30 and the second feeding system 40 are arranged on the circuit board, in other words, the first feeding system 30 in the first feeding system 100a of the first feeding mode The matching system 32 (see FIG. 18 ), the second matching system 42 (see FIG. 18 ) in the second feeding system 40 , and the matching circuit 20 are all connected with the first antenna module 100a of the second feeding method. The first matching system 32 in the first feeding system 30 (see FIG. 18 ), the second matching system 42 in the second feeding system 40 (see FIG. 18 ), and the matching circuit 20 are different. Therefore, the antenna matching and working principles of the first antenna module 100 a of the first feeding method and the first antenna module 100 a of the second feeding method are different.

Since the GPS-L5 frequency band and the first LB frequency band have different effective electrical lengths for the radiator, by adjusting the matching circuit 20, a part of the first radiator 10 can be effectively adjusted to support the GPS-L5 frequency band or be adjusted to support First LB band. For the specific adjustment method of the matching circuit 20, including but not limited to adjusting the capacitance value of the matching circuit 20, or adjusting the inductance value of the matching circuit 20, or adjusting the matching circuit 20 from a capacitance to an inductance, or adjusting the matching circuit 20 from an inductance for capacitors etc.

The first antenna module 100a of the first feeding mode and the first antenna module 100a of the second feeding mode will be specifically illustrated below.

In the first antenna module 100a of the first feeding mode, the second feeding system 40 is used to excite the first radiator 10 to at least send and receive the GPS frequency band. GPS frequency bands include but are not limited to GPS-L1 frequency band and/or GPS-L5 frequency band.

The working mode of the GPS frequency band includes a resonant mode resonating between the matching point B and the free end 122 . In this embodiment, the GPS-L5 frequency band is taken as an example for illustration. Specifically, the working mode of the GPS-L5 frequency band includes a 1/4 wavelength mode that resonates between the matching point B and the free end 122 .

Please refer to FIG. 12 , the current corresponding to the resonant mode generated by the RF signal in the GPS-L5 frequency band fed by the second feeding system 40 is mainly distributed between the matching point B and the free end 122 . As shown by the dotted arrow in FIG. 12 , the resonant current generated by the radio frequency signal in the GPS-L5 frequency band flows from the free end 122 to the matching point B. As shown in FIG.

By designing the effective electrical length between the matching point B and the free end 122, the effective electrical length between the matching point B and the free end 122 corresponds to the GPS-L5 frequency band 1/4 medium wavelength. Wherein, the "correspondence" can be understood as the effective electrical length between the matching point B and the free end 122 is about 1/4 of the medium wavelength of the GPS-L5 frequency band. Correspondingly, the effective electrical length from the matching point B to the free end 122 is about 1/4 of the medium wavelength of the GPS-L5 frequency band. Wherein, the 1/4 wavelength mode may also be referred to as a base state, and the base state has higher antenna efficiency, thereby improving the transceiving efficiency for the GPS-L5 frequency band.

Wherein, the radiator section between the matching point B and the free end 122 is farther away from the first sub-radiator 11 than the radiator section between the matching point B and the first coupling end 121 . When the antenna assembly 100 is applied to the electronic device 1000 , the radiator segment between the matching point B and the free end 122 is relatively close to the top of the electronic device 1000 . Since the user usually navigates in a vertical screen when using the GPS frequency band, the probability of a horizontal screen is extremely low. Thus, setting the antenna for transmitting and receiving the GPS frequency band near the top of the electronic device 1000 can make the electronic device 1000 In the vertical screen holding state, the antenna for transmitting and receiving the GPS frequency band is not easily blocked by the hand. In addition, the GPS frequency band is designed at a position closer to the corner, which can well stimulate the circuit board 500 (or reference ground system GND) on the horizontal current mode (current mode along the X-axis direction), so that the efficiency of the upper hemisphere of the electronic device 1000 is relatively high, and it can receive signals from more satellites during navigation, improving the signal quality of the GPS frequency band.

Please refer to FIG. 13. FIG. 13 is the efficiency curve of the first antenna module 100a supporting GPS-L5+MHB+Wi-Fi2.4G+N78+N79/Wi-Fi 5G in the first feeding mode of the present application. It can be seen from Figure 13 that the efficiency of each frequency band is above -10dB. Compared with the antenna modules provided in the general technology, the first antenna module 100a provided by this application supports more frequency bands, and the first radiator 10 utilizes The efficiency is high, the frame area occupied by the first radiator 10 is relatively small, and each frequency band has high efficiency.

In the first antenna module 100a of the second feeding mode, the second feeding system 40 is used to excite the first radiator 10 to at least send and receive the first LB frequency band. The first LB frequency band includes some frequency bands in 703MHz-960MHz, for example, B20, N28 and so on.

The working mode of the first LB frequency band includes a resonant mode resonating between the matching point B and the free end 122 . Specifically, the working mode of the first LB frequency band includes a 1/4 wavelength mode that resonates between the matching point B and the free end 122 .

Please refer to FIG. 14 , the current corresponding to the resonant mode generated by the RF signal in the first LB frequency band fed by the second feeding system 40 is mainly distributed between the matching point B and the free end 122 . As shown by the dotted arrow in FIG. 14 , the resonant current generated by the radio frequency signal in the first LB frequency band flows from the free end 122 to the matching point B. As shown in FIG. Of course, there will also be a small part of the current towards the first feeding point A.

By designing the effective electrical length between the matching point B and the free end 122, the effective electrical length between the matching point B and the free end 122 corresponds to the first LB frequency band 1/4 medium wavelength. Wherein, the "correspondence" can be understood as the effective electrical length between the matching point B and the free end 122 is about 1/4 of the medium wavelength of the first LB frequency band. Correspondingly, the effective electrical length from the matching point B to the free end 122 is about 1/4 of the medium wavelength of the first LB frequency band. Wherein, the 1/4 wavelength mode may also be referred to as a base state, and the base state has higher antenna efficiency, thereby improving the transceiving efficiency for the first LB frequency band.

The first LB frequency band includes at least one of a first receiving frequency band, a first transmitting frequency band, a second transmitting frequency band, and a second receiving frequency band.

Please refer to FIG. 15 , when the antenna assembly 100 has the first antenna module 100a of the second feeding mode, the antenna assembly 100 further includes a second antenna module 100b. The second antenna module 100b includes a second radiator 10b. Optionally, the second radiator 10b is a conductive frame radiator. The second radiator 10b is used to support the second LB frequency band. The frequency band combination formed by the second LB frequency band and the first LB frequency band includes the first receiving frequency band, the first transmitting frequency band, the second transmitting frequency band, and the second receiving frequency band.

Wherein, the first receiving frequency band is the receiving frequency band of the first frequency band, and the second receiving frequency band is the receiving frequency band of the second frequency band. Wherein, the first transmitting frequency band is the transmitting frequency band of the first frequency band, and the second transmitting frequency band is the transmitting frequency band of the second frequency band, and the first frequency band and the second frequency band are different frequency bands .

Specifically, the first antenna module 100a cooperates with the second antenna module 100b to support the full bandwidth (including receiving bandwidth and transmitting bandwidth) of the first frequency band and the second frequency band.

In the first optional implementation manner, the first antenna module 100a supports the first receiving frequency band and the first transmitting frequency band; the second antenna module 100b supports the second receiving frequency band and the second transmitting frequency band.

The first frequency band and the second frequency band include but are not limited to any two of B5, B8, N5, N8, N20, N28, N28, and B20.

Further, referring to FIG. 15 , when the antenna assembly 100 has the first antenna module 100a of the second feeding mode, the antenna assembly 100 further includes a third antenna module 100c. The third antenna module 100c includes a third radiator 10c. Optionally, the third radiator 10c is a conductive frame radiator. The third radiator 10c is used to support the third LB frequency band. The third LB frequency band includes a transmitting frequency band of the first frequency band, a receiving frequency band of the first frequency band, a transmitting frequency band of the second frequency band, and a receiving frequency band of the second frequency band.

For example, the third radiator 10c supports a first receiving frequency band and a transmitting frequency band, and a second receiving frequency band and a second transmitting frequency band.

In this way, the first antenna module 100a, the second antenna module 100b, and the third antenna module 100c cooperate to support the full bandwidth of N28 and the full bandwidth of B20.

In general technology, with the popularization of the curved screen of the electronic device 1000, the borders on the left and right sides of the electronic device 1000 become narrower, and the clearance environment becomes poorer, resulting in the Bandwidth becomes smaller. For example, based on -10dB efficiency, it can barely support a bandwidth of 80MHz.

Today, some operators need to support two low frequency bands, such as B20+N28 non-independent networking (NSA). This requires that both low-frequency antennas support the bandwidths of the B20 and N28 frequency bands at the same time. Due to the limitation of the location of the antenna on the electronic device 1000 and the need to install a specific antenna in some specific places, when the low-frequency antenna is set on the left or right frame of the electronic device 1000, due to the narrowing of the frame and the change of the clearance environment Poor, the low-frequency antenna cannot support the bandwidth of the B20 and N28 frequency bands at the same time. If an adjustable capacitor is used on the low-frequency antenna to increase the bandwidth, even so, the efficiency in these two frequency bands can only be about -12dB, and due to the use of the adjustable capacitor, the cost is also increased, which is not conducive to the electronic equipment 1000 Mass production.

For example, the first frequency band is B20, and the second frequency band is N28. Among them, the transmitting frequency band of the B20 is 832MHz-862MHz, and the receiving frequency band of the B20 is 791MHz-821MHz. The transmitting frequency band of N28 is 703MHz～748MHz, and the receiving frequency band of B20 is 758MHz～803MHz. Because the receiving frequency band of B20 is similar to that of N28. Therefore, the same low-frequency antenna can be used to support the receiving frequency band of B20 and the receiving frequency band of N28.

This application provides three low-frequency antennas (a part of the first antenna module 100a, the second antenna module 100b and the third antenna module 100c) that jointly support the above-mentioned B20 frequency band and N28 frequency band. Among them, the three low-frequency In the antenna, a low-frequency antenna (such as a part of the first antenna module 100a) supports the N28 transmission frequency band + N28 reception frequency band, a low-frequency antenna supports (such as the second antenna module 100b) B20 transmission frequency band + B20 reception frequency band, and the other low-frequency The antenna (such as the third antenna module 100c) is used as a diversity receiving antenna for two frequency bands to support the N28 receiving frequency band+B20 receiving frequency band, so that one antenna transmits and two antennas receive for each frequency band, wherein two receive One of the antennas is the main set receiving antenna, and the other is the diversity receiving antenna. This application distributes the receiving frequency band and transmitting frequency band of the first frequency band, and the receiving frequency band and transmitting frequency band of the second frequency band to the first antenna module 100a, the second antenna module 100b and the third antenna module 100c by design, without The first frequency band and the second frequency band are simultaneously supported by one antenna module, so as to meet the bandwidth support requirement that one antenna transmits and two antennas receive in each of the two frequency bands.

In addition, in addition to supporting the first frequency band or the second frequency band, the first antenna module 100a can also support MHB+Wi-Fi2.4G+N78+N79/Wi-Fi 5G, so that the first antenna module 100a Not only can it support two low-frequency bands with the second antenna module 100b, but also uses the split feed technology, and different modes on a radiator can share a structural member (frame), which further broadens the supportable frequency bands and realizes It supports MHB+Wi-Fi 2.4G+N78+N79/Wi-Fi5G, greatly increasing the bandwidth supported by the first antenna module 100a.

Please refer to Fig. 16, Fig. 16 is the S11 curve of the first antenna module 100a supporting LB+MHB+Wi-Fi2.4G+N78+N79/Wi-Fi 5G in the second feeding mode of the present application. From Fig. 16, we can see the S11 of each frequency band, where there are 7 resonant modes from left to right in Fig. 16 (the resonant mode is the trough in the curve). Wherein, the first resonant mode a is the resonant mode supported by the first antenna module 100a in the LB frequency band, and is also a 1/4 wavelength mode resonating between the free end 122 and the matching point B. The second resonance mode b is the resonance mode of the first antenna module 100 a supporting the MB frequency band, and is also a 1/2 wavelength mode that resonates between the first coupling slot 13 and the second coupling slot 16 . The third resonant mode c is the resonant mode that the first antenna module 100a supports HB frequency band+WiFi 2.4G frequency band, and is also a 1/4 wavelength mode that resonates between the first coupling slot 13 and the first ground terminal 111 . The fourth resonant mode d and the fifth resonant mode e are the resonant modes supported by the first antenna module 100a in the N78 frequency band, which are the 1-fold wavelength mode resonating between the first coupling slot 13 and the second coupling slot 16. The 1/2 wavelength mode resonating on the bracket radiator 17; or, the fourth resonance mode d and the fifth resonance mode e are respectively the 1/2 wavelength mode resonating on the bracket radiator 17 and resonating at the first coupling 1x wavelength mode between the slot 13 and the second coupling slot 16 . The sixth resonance mode f and the seventh resonance mode h are the resonance modes of the first antenna module 100a supporting the N79 frequency band or the Wi-Fi 5G frequency band, which are the resonance modes on the resonant main radiator 12 and the resonant radiator on the bracket The resonant mode on 17, or the sixth resonant mode f and the seventh resonant mode h are the resonant mode on the resonant main radiator 12 and the resonant mode on the bracket radiator 17 respectively.

It is worth noting that the N78 frequency band is 3.3GHz-3.8GHz, the bandwidth is very wide, and it is difficult to cover one resonance mode. It can be clearly seen from Figure 16 that the first antenna module 100a provided by this application uses two modes to cover the N78 , can cover the full bandwidth of N78.

Please refer to FIG. 17. FIG. 17 shows the simulation efficiency of each frequency band supported by the first antenna module 100a of the present application as LB+MHB+Wi-Fi 2.4G+N78+N79/Wi-Fi5G. It can be seen from Figure 17 that the efficiency of each frequency band is above -10dB. Compared with the antenna modules provided in the general technology, the first antenna module 100a provided by this application supports more frequency bands, and the utilization rate of the first radiator is High, the area of the frame occupied by the first radiator is relatively small, and each frequency band has high efficiency.

In other embodiments, the second feeding system 40 is also used to stimulate the first radiator 10 to send and receive electromagnetic wave signals in the N78 frequency band. In other words, the N78 frequency band can also be fed into the first radiator 10 by the second feed system 40, so that the N78 frequency band and the MB frequency band are respectively fed into the first radiator by different feed systems. Body 10, in order to increase the antenna form of antenna assembly 100.

Optionally, the second feeding system 40 is also used to excite the first radiator 10 to send and receive electromagnetic wave signals in the N79 frequency band. The first feeding system 30 is used to stimulate the first radiator 10 to send and receive electromagnetic wave signals in the Wi-Fi 5G frequency band. Since the N79 frequency band and the Wi-Fi 5G frequency band partially overlap, if the N79 frequency band and the Wi-Fi 5G frequency band are fed through the same feed system, the N79 frequency band and the Wi-Fi 5G frequency band cannot be separated. Fi 5G frequency band. By feeding the N79 frequency band and the Wi-Fi 5G frequency band through two different feeding systems, the first radiator 10 can simultaneously transmit and receive the N79 frequency band and the Wi-Fi 5G frequency band, further The mobile communication signals supported by the antenna assembly 100 and the supported Wi-Fi frequency bands are greatly increased. In other embodiments, the first feeding system 30 can also be used to stimulate the first radiator 10 to send and receive electromagnetic wave signals in the N79 frequency band, and the second feeding system 40 can stimulate the first radiator 10 to transmit and receive Describe the electromagnetic wave signal in the Wi-Fi 5G frequency band.

Since the current of the MB frequency band is mainly concentrated from the first coupling slot 13 to the matching point B, and the current of the GPS-L5 frequency band is concentrated from the second coupling slot 16 to the matching point B, thus, the matching circuit 20 realizes 1/4 of the MB frequency band Both the wavelength mode and the 1/4 wavelength mode of the GPS-L5 frequency band act on the main radiator 12 without interfering with each other, increasing the number of frequency bands supported by the main radiator 12 and increasing the antenna bandwidth supported by the antenna assembly 100 .

Please refer to FIG. 14 , when the signal fed by the second feeding system 40 is the first LB frequency band, the matching circuit 20 can also achieve matching to ground (low impedance to ground) for the first LB frequency band. In other words, the resonance current in the 1/4 wavelength mode generated on the main radiator 12 by the first LB frequency band fed by the second feeding system 40 flows to the reference ground system GND through the matching circuit 20 . In this way, a new current loop is formed to stimulate the 1/4 wavelength mode with higher efficiency and promote the transmission and reception of the LB frequency band.

For example, when the switched inductance value is smaller, the resonance frequency shifts more toward the high frequency end; when the switched capacitance value is larger, the resonance frequency shifts more toward the low frequency end. In this way, the frequency band supported by the main radiator 12 is tuned, and the efficiency of the frequency band supported by the antenna assembly 100 is optimized.

Please refer to FIG. 24 , the present application provides an antenna that can support Wi-Fi signals + 4G signals + 5G signals on the left side frame (third side frame 313 ) on the back of the electronic device 1000 near the top (first side frame 311 ). (The antenna in this application corresponds to the first radiator 10), so that the electronic device 1000 can freely enjoy scenes such as horizontal screen games or videos under Wi-Fi signals, 4G signals, and 5G signals. The following uses a horizontal screen game scene as an example for illustration.

Please refer to Fig. 18 and Fig. 23, there are two feed points (namely the first feed point A and the second feed point D) near the top of the left side frame on the back of the electronic device 1000, the first feed point in the horizontal screen game mode The feeding point A is electrically connected to the first feeding system 30. In order to obtain good horizontal screen game performance, the distance from the first feeding point A to the top of the electronic device 1000 must be at least 20 mm, or even more than 30 mm. The antenna radiation of the system 30 mainly relies on the first radiator 10 below the matching point B (the first radiator 10 between the matching point B and the first ground terminal 111), and this part of the first radiator 10 is located on the back of the electronic device 1000 The middle position of the left side frame is basically out of reach when the screen is held in landscape mode, so as to achieve a better network speed in the scene of holding the screen in landscape mode.

Please refer to FIG. 18 and FIG. 23. In this example, the distance from the first feeding system 30 to the top of the electronic device 1000 is about 45mm or more, and the signal frequency band fed by the first feeding system 30 is LTE MHB (4G medium and high frequency band)+ The combined frequency band of NR MHB (5G medium and high frequency band) + Wi-Fi 2.4G + N78 + N79. The signal fed by the second feed system 40 is the GPS-L5 frequency band. The above signal frequency bands are just examples, and the frequency bands can be added or deleted.

Please refer to Fig. 18 and Fig. 23, since the 1/4 wavelength mode of the MB frequency band is the main mode, the main radiation part of the main mode (the first radiator 10 between the matching point B and the first coupling end 121) is far away from the top of the mobile phone. The distance is greater than 30, it is difficult to be held when the screen is horizontal, so the MB frequency band will not be affected when the screen is horizontal. Since the first sub-radiator 11 is closer to the middle of the mobile phone, it is completely impossible to be held when the screen is horizontal, and all LTE HB frequency bands (4G high frequency) and NR HB frequency bands (5G high frequency) will not be affected by handholding. Since the main modes of the N78 and N79 frequency bands are on the bracket radiator 17, and the bracket radiator 17 is inside the mobile phone casing 300, not the frame 310, and cannot be held by hand, the performance of the N78 and N79 frequency bands is good when the screen is horizontal. The GPS-L5 frequency band is designed on the upper part of the mobile phone, and it is easy to be held by the hand when the screen is horizontal, because the GPS-L5 frequency band is usually used in vertical screen navigation, and the probability of horizontal screen is extremely low. The GPS-L5 frequency band is designed in the The position closer to the corner can well stimulate the lateral current mode of the PCB (such as the circuit board where the reference ground system GND is located), so that the efficiency of the upper hemisphere is higher, and more satellite signals can be received during navigation. It should be emphasized that since the first feed system 30 and the second feed system 40 are fed on the first radiator 10 of the same frame 310, the first sub radiator 11, the main radiator 12 and the second sub radiator The radiator 15 belongs to a co-body antenna, which enhances the bandwidth of the game antenna of the entire first feeding system 30 .

This application designed the antenna combination of the frame antenna + bracket antenna, and designed a multi-frequency antenna on the left side of the back of the electronic device 1000, including the combined frequency band of LTE MHB+NR MHB+Wi-Fi 2.4G+N78+N79, the second feeder The electrical system 40 is also designed for the GPS-L5 frequency band, which is the antenna assembly 100 that supports relatively more frequency bands in the antenna assembly 100 that is currently held in a horizontal screen and will not block the antenna signal.

This application designs a common antenna with slots at both ends, together with the bracket antenna, so that the first radiator 10 of the antenna assembly 100 is very long, basically it can cover the Wide bandwidth, if an adjustable device is needed, an adjustable device can be added below the matching point B to better cover each frequency band. Since the Wi-Fi 2.4G frequency band is generated by the parasitic 1/4 wavelength mode on the first sub-radiator 11, which belongs to the inherent length, when the adjustable device on the matching point B is tuned, there is still Wi-Fi 2.4G The performance of the frequency band ensures that the Wi-Fi 2.4G frequency band can be used simultaneously with the MHB frequency band in any state.

The above are some implementations of the present application. It should be pointed out that those skilled in the art can make some improvements and modifications without departing from the principles of the present application. These improvements and modifications are also regarded as For the scope of protection of this application.
