Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Currently, in the frequency bands supported by electronic devices (such as mobile phones), B5/B8/B12/B13/B20/B28/B71 are low frequencies, and the frequency range is from 600Mhz to 960 Mhz; B1/B2/B3/B4/B39/B66 is an intermediate frequency, and the frequency range is from 1710MHz to 2200 Mhz; B7/B30/B38/B40/B41 is high frequency, and the frequency range is 2300Mhz-2690 Mhz; the B4/B66 band has a characteristic that the frequency used for transmission is far away from the frequency used for reception, such as B4 transmission frequency 1710-. On the diversity antenna, the conventional antenna also needs one antenna to support the frequencies of the low frequency, the intermediate frequency and the high frequency, the required bandwidth is very wide, and in the overall screen project, the realized clearance area is very small, so that the diversity antenna cannot realize good performance.
Based on this, embodiments of the present invention provide an antenna structure and an electronic device, which are described in detail below.
First, an embodiment of the present invention provides an antenna structure, where the antenna structure includes a metal frame, a lower antenna for implementing main-set transmission and reception is disposed at a lower end of the metal frame, and an upper antenna for implementing diversity reception is disposed at an upper end of the metal frame; at least one breakpoint is arranged at the position of the metal frame body corresponding to the upper antenna or the lower antenna, and the upper antenna or the lower antenna is divided into a plurality of antennas so as to realize the functions of the antennas in different frequency bands respectively.
As shown in fig. 1, which is a schematic structural diagram of an embodiment of an antenna structure in an embodiment of the present invention, the antenna structure includes a metal frame 101, a lower antenna for implementing main set transmission and reception is disposed at a lower end of the metal frame 101, an upper antenna for implementing diversity reception is disposed at an upper end of the metal frame 101, the lower antenna may be provided with a corresponding lower antenna feed point, and the upper antenna may be provided with a corresponding upper antenna feed point;
at least one breakpoint is arranged at the position of the metal frame body corresponding to the upper antenna or the lower antenna, and the upper antenna or the lower antenna is divided into a plurality of antennas so as to realize the functions of the antennas in different frequency bands respectively.
The embodiment of the invention is provided with at least one breakpoint in the upper antenna or the lower antenna, so that the upper antenna or the lower antenna can be divided into a plurality of antennas, and the frequency bands supported by the upper antenna or the lower antenna are divided into different antennas, thereby respectively realizing the antenna functions of different frequency bands and improving the antenna performance.
In addition, the metal frame 101 can be aluminum alloy or zinc alloy, the upper end and the lower end of the metal frame 101 are provided with the upper antenna and the lower antenna, and the antenna breakpoints are located at the top and the bottom of the metal frame 101, so that the situation that when a user holds the electronic device by hand, the antenna breakpoints are held, the antenna is short-circuited, and signals are seriously attenuated is avoided.
In this embodiment of the present invention, the metal frame 101 corresponding to the upper antenna or the lower antenna is provided with at least one breakpoint, where the metal frame 101 corresponding to the upper antenna or the lower antenna is provided with at least one breakpoint, or the metal frame 101 corresponding to the upper antenna and the lower antenna is provided with at least one breakpoint, and both the above manners can separate at least one of the upper antenna or the lower antenna into a plurality of antennas, so as to implement the antenna functions of different frequency bands and improve the overall performance of the antenna structure.
In the embodiment of the invention, the width of each breakpoint can be set to be 1.4-1.8 mm, preferably 1.6mm, the antenna performance is better facilitated by the width, the metal frame body is completely disconnected at the breakpoint, plastic insulation can be filled in the disconnection space, and the realization of the antenna performance depends on the mutual coupling between metals at two sides of the breakpoint, so that the metal frame body needs to be disconnected and has a certain distance. And the metal frame body is disconnected, and the antennas using different sections of metal frame bodies have good isolation. When the metal frame body position that last antenna and lower antenna correspond is provided with the breakpoint of the same quantity, the breakpoint can be the symmetric position to guarantee that whole pleasing to the eye. For example, two breakpoints are arranged at the position of the metal frame body 101 corresponding to the upper antenna, two breakpoints are arranged at the position of the metal frame body 101 corresponding to the lower antenna, and at the moment, the four breakpoints can be symmetrically arranged to ensure the overall attractiveness.
In some embodiments of the present invention, the upper antenna is all or a part of the upper end of the metal frame 101, and the lower antenna is all or a part of the upper end of the metal frame 101.
According to the antenna performance implementation characteristics, the radiator required by low frequency is long, the radiator required by medium-high frequency is short, and the radiator of low frequency naturally generates a secondary resonance to implement partial medium-frequency performance, so that the frequency band supported by the antenna can be split into different antennas to implement, and different layout positions of the antenna are allocated according to the structural characteristics of the electronic equipment, thereby implementing better antenna performance. Specifically, the lower antenna is a part of the lower end of the metal frame 101, as shown in fig. 1, a first break point 102 and a second break point 103 may be disposed in the metal frame 101 corresponding to the lower antenna, the first break point 102 separates the lower antenna into a first antenna 104 and a second antenna 105, and the second break point 103 separates the first antenna 104 from the rest of the lower end of the metal frame 101.
The first antenna 104 is configured to implement a main set transmitting and receiving function of a preset low frequency, a main set transmitting and receiving function of a first preset intermediate frequency, and a main set transmitting function of a second preset intermediate frequency. The preset low frequency comprises frequency bands such as B5/B8/B12/B13/B20/B28/B71 and the like. The first preset intermediate frequency and the second preset intermediate frequency constitute a complete preset intermediate frequency (e.g., an intermediate frequency for mobile phone communication), for example, the first preset intermediate frequency includes frequency bands such as B2/B3/B39, and the second preset intermediate frequency includes frequency bands such as B1/B4/B66. Further, according to the characteristics of the antenna, the low-frequency radiator can naturally generate a part of 2-order resonance, and the part of 2-order resonance can be used for realizing the transmission and reception performance of the B2/B3/B39 main set and the transmission (no reception) performance of the B1/B4/B66 main set.
Furthermore, the transmitting and receiving frequency of each frequency band in the first preset intermediate frequency is 1850-1990Mhz, and the transmitting frequency of each frequency band in the second preset intermediate frequency is 1710-1980 Mhz. For example, when the first preset intermediate frequency is a frequency band such as B2/B3/B39, and the second preset intermediate frequency is a frequency band such as B1/B4/B66, the transmission frequency of B1 is 1920-.
In the embodiment of the present invention, the second antenna 105 may be configured to implement a main set receiving function of the second preset intermediate frequency and a main set transmitting and receiving function of a preset high frequency. The preset high frequency may include frequency bands of B7/B30/B38/B40/B41, etc., and the second preset intermediate frequency may include frequency bands of B1/B4/B66, etc., as described above.
Because the frequencies supported by the second antenna 105 are the intermediate frequency B1/B4/B66 and the high frequency B7/B30/B38/B40/B41, the frequencies supported by the second antenna 105 are both relatively high, and the higher the frequency is, the shorter the required electrical length of the radiator is, and therefore, the length of the metal frame corresponding to the first antenna 104 is longer than that of the metal frame corresponding to the second antenna 105. In the embodiment of the present invention, as shown in fig. 1, the length of the metal frame at the middle section of the bottom of the metal frame 101 is longer, and the metal frame can be used to implement the low frequency performance supported by the first antenna 104.
Further, the length of the first antenna 104 may be set at 42-48 mm, preferably 45mm, which is not suitable for too long, and may affect the antenna performance of the second antenna 105. Because the section of metal frame is mainly used for realizing low-frequency performance, the response resonance of the metal frame is just within the range of 600-900MHz within 45mm, and if the length of the metal frame is too long, the response resonance shifts to the low-frequency band, which results in poor performance of B5 and other bands around 800-900MHz, and is difficult to optimize. The length of the second antenna 105 may be set to be greater than 18mm, and the length of this part is as long as possible, which is beneficial to implement the antenna performance, because this section of metal frame is mainly used to implement the medium-high frequency antenna performance, and the length of 18mm is not enough to respond to resonance, but because of the design reason of the electronic device, this section of metal frame may not reach enough length, and needs to add additional LDS routing to complement, which is described in detail in the following embodiments.
Because the first antenna 104 only needs to realize the performance of the 1.7G-2GHz frequency band at the intermediate frequency in addition to the low frequency, and needs to realize the frequency from 1.7G-2.2GHz as compared with the conventional antenna, the bandwidth needing to be supported is reduced from 500Mhz to 300Mhz, which is reduced by 2/5, and the required bandwidth is narrow, a higher single-frequency performance can be realized, and more space can be given to the low frequency at the same time, so that the performance of the low-frequency antenna is higher than that of the conventional antenna. The B4/B66 receive portion is implemented from a 100Mhz bandwidth of 2.1G-2.2GHz via another second antenna 105. Through the arrangement of the first antenna 104 and the second antenna 105, the lower antenna can respectively realize the antenna functions of low frequency, medium frequency and high frequency bands, and the antenna functions are not interfered with each other, so that the overall antenna performance of the lower antenna is improved.
In order to avoid interference between the first antenna 104 and the second antenna 105 and increase the isolation between the first antenna 104 and the second antenna 105, the feed point 107 of the second antenna 105 may be disposed far from the feed point 106 of the first antenna 104, specifically, the feed point 107 of the second antenna may be disposed at an end of the second antenna 105, and the feed point 106 of the first antenna may be disposed at an end of the first antenna 104 and far from the feed point 107 of the second antenna. As shown in fig. 1, the feed point 107 of the second antenna is disposed at the left end of the second antenna 105, and the feed point 106 of the first antenna is disposed at the right end of the first antenna 104.
Similarly, the upper antenna may be all or a part of the upper end of the metal frame 101, in some embodiments of the present invention, as shown in fig. 1, a third break 108 and a fourth break 109 may be disposed in the metal frame corresponding to the lower antenna, where the third break 108 and the fourth break 109 separate the upper antenna into a third antenna 110, a fourth antenna 111, and a fifth antenna 112, and the fourth antenna 111 and the fifth antenna 112 are located on two sides of the third antenna 110.
In this embodiment of the present invention, the third antenna 110 may be configured to implement a preset low-frequency diversity receiving function and a third preset intermediate-frequency diversity receiving function; the fourth antenna 111 may be configured to implement a GPS antenna function, a fourth preset intermediate frequency diversity reception function, and a preset high frequency diversity reception function; the fifth antenna may be used to implement WI-FI antenna functionality. The preset low frequency can also comprise frequency bands such as B5/B8/B12/B20/B28/B13/B71, and the preset high frequency can also comprise frequency bands such as B30/B7/B38/B40/B41. The third preset intermediate frequency and the fourth preset intermediate frequency constitute a complete preset intermediate frequency band (e.g., an intermediate frequency band for mobile phone communication), for example, the third preset intermediate frequency includes a B2 frequency band, and the fourth preset intermediate frequency includes B1/B4/B66/B39 frequency bands. Since the frequencies of B1/B4/B66/B39/B30/B7/B38/B40/B41 and GPS are higher, the same antenna (the fourth antenna 111) can be used, and the 1575Mhz frequency used by the GPS antenna is a distance from the frequency used by B1/B4/B66/B39/B30/B7/B38/B40/B41, which can be separated by a frequency divider in the RF architecture. The fifth antenna 112 in the embodiment of the present invention may be separately configured to implement a WI-FI antenna function, for example, implement a WI-FI 2.4G antenna function.
The upper antenna also utilizes the characteristic that the physical lengths of the metal frame bodies required by different frequencies are different, and reasonable splitting and combination are realized among different antennas. In order to achieve better low frequency performance, most of the medium and high frequencies are separated and combined with the GPS antenna to form the fourth antenna 111. B2 is implemented by using the second resonance naturally generated by the low frequency part, and can remain on the low frequency antenna (third antenna 110) without affecting the low frequency performance implementation. Through the arrangement of the third antenna 110, the fourth antenna 111 and the fifth antenna 112, the antenna functions of low frequency, medium frequency, high frequency, GPS antenna, Wi-Fi antenna and other frequency bands can be respectively realized on the upper antenna, and the mutual interference is avoided, so that the overall antenna performance of the upper antenna is improved.
Similarly, the length of the third antenna 110 may be set to 42-48 mm, preferably 45mm, which is not suitable for too long, and may affect the antenna performance of the third antenna 110. Because the section of metal frame is mainly used for realizing low-frequency performance, the response resonance of the metal frame is just within the range of 600-900MHz within 45mm, and if the length of the metal frame is too long, the response resonance shifts to the low-frequency band, which results in poor performance of B5 and other bands around 800-900MHz, and is difficult to optimize. The length of the fourth antenna 111 can be set to be larger than 18mm, and the length of the part is as long as possible, which is beneficial to the realization of antenna performance, because the section of metal frame is mainly used for realizing medium-high frequency antenna performance, the length of 18mm is not enough to respond to resonance, but because of the design reason of electronic equipment, the section of metal frame may not reach enough length, and additional LDS routing is required to be added for complement, which is detailed in the following description.
Similarly, to avoid interference between the antennas, the isolation between the antennas is increased, specifically, as shown in fig. 1, in the embodiment of the present invention, the feed point 114 of the fourth antenna may be disposed at the right end of the fourth antenna 111, the feed point 113 of the third antenna may be disposed at the left end of the third antenna 110, and the feed point 115 of the fifth antenna may be disposed at the right end of the fifth antenna 112.
In some embodiments of the above-mentioned designs of the antennas, sometimes the implementation of the antenna function cannot be guaranteed only by using the metal frame, and as for the second antenna 105 and the fourth antenna 111, extra Laser-Direct-structuring (Laser-Direct-structuring) routing needs to be added sometimes to complement the routing length, or to adjust the routing mode to reach an ideal resonance or impedance position, so as to obtain an ideal antenna performance. Therefore, the upper part and the lower part of the metal frame body can be respectively provided with an antenna support, and the antenna wires are laser-etched on the antenna supports in an LDS mode and are connected with the metal frame through special elastic pieces in a switching mode. Specifically, a first antenna support is arranged at the lower end of the metal frame, the antenna wiring of the second antenna 105 is laser-etched on the first antenna support in an LDS mode, and the first antenna support is connected with the metal frame 101 through elastic pieces in a switching mode. Further, a second antenna support may be disposed at the lower end of the metal frame, antenna wires of the fourth antenna 111 and the fifth antenna 112 are laser-etched on the second antenna support in an LDS manner, and the second antenna support is connected to the metal frame 101 through elastic pieces.
It should be noted that, in the embodiment of the present invention, in order to implement the above antenna structure, a Radio Frequency architecture also needs to be correspondingly improved, and a corresponding Frequency band or channel is split and connected to a corresponding antenna feed point through a Radio Frequency (RF) feeder.
