The following describes the antenna module and the electronic device in detail with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 1 is a schematic structural diagram of an embodiment of an antenna module provided in the present application, the antenna module provided in the present application is disposed on a first PCB layer 10 shown in fig. 1, the first PCB layer takes a rectangular shape as an example, a first clearance area 12 is disposed at a first edge below the first PCB layer in fig. 1, no copper is coated on the first clearance area 12, and copper is coated on a non-clearance area 11.

In some embodiments, fig. 2 is a schematic structural diagram of an embodiment of an antenna module provided in the present application, and as shown in fig. 2, the antenna module specifically includes: a bluetooth antenna 101, a first Wi-Fi antenna 102A, and a second Wi-Fi antenna 102B. The bluetooth antenna 101, the first Wi-Fi antenna 102A, and the second Wi-Fi antenna 102B are all disposed in the first clearance area 12 on the first PCB layer as shown in fig. 1, and the first Wi-Fi antenna 102A, the bluetooth antenna 101, and the second Wi-Fi antenna 102B are sequentially arranged at intervals.

In some embodiments, there is a first separation D1 between the first Wi-Fi antenna 102A and the bluetooth antenna 101 and a second separation D2 between the bluetooth antenna 101 and the second Wi-Fi antenna 102B. Specifically, when any one of the Wi-Fi antennas in the antenna module performs communication, in order to reduce the influence of the bluetooth antenna 101, which is a metal body at this time, on the Wi-Fi antenna, the first interval D1 may be set to be greater than or equal to 4mm, and the second interval D2 may be set to be greater than or equal to 4mm, and the first interval D1 and the second interval D2 may be the same or different, and may specifically be set according to antennas on both sides of the interval. That is, the bluetooth antenna 101 can perform bluetooth communication and can also be used as an isolation antenna between the first Wi-Fi antenna 102A and the second Wi-Fi antenna 102B, so the bluetooth antenna 101 can be referred to as a "decoupled antenna".

Fig. 3 is a schematic structural diagram of an embodiment of the bluetooth antenna provided in the present application, and the bluetooth antenna shown in fig. 3 can be applied to the antenna module shown in fig. 2. This bluetooth antenna 101 includes: a power feeding unit 1011, a first grounding unit 1012, and a second grounding unit 1013 arranged at intervals in this order. In fig. 3, the power feeding unit 1011, the first ground unit 1012, and the second ground unit 1013 are each rectangular, and these three rectangular portions are arranged in parallel in the longitudinal direction X.

In some embodiments, the first end of the power feeding portion 1011, the first end of the first ground portion 1012, and the first end of the second ground portion 1013 are connected by a connection portion 1014, such that the power feeding portion 1011, the first ground portion 1012, the second ground portion 1013, and the connection portion 1014 constitute an "M" shaped structure.

A second end of the feeding section 1011 is connected to a port 1014 through a first impedance matching module 1015, and the port 1014 can be used to connect a line (e.g., RF in) on a first PCB layer, so that the port 1014 can be used as a feeding point of the bluetooth antenna. At this time, the circuit on the first PCB layer may transmit the electrical signal to the feeding portion 1011 through feeding and be converted into an electromagnetic wave signal by the bluetooth antenna and then transmit the electromagnetic wave signal, or the bluetooth antenna may receive the electromagnetic wave signal and be converted into an electrical signal and transmit the electrical signal to the circuit on the first PCB layer through the port 1014.

In some embodiments, a slot facing the bluetooth antenna 101 is further disposed on the non-clearance region 11 of the first PCB layer as shown in fig. 3, the first impedance matching module 1015 and the port 1014 are disposed in the slot, and the first impedance matching module 1015 and the port 1014 are spaced apart from the non-clearance region on two sides thereof without direct contact.

The second end of the first ground part 1012 is connected to the non-clearance area 11 on the first PCB layer through the first connection structure 10121, and the second end of the second ground part 1013 is also connected to the non-clearance area 11 on the first PCB layer through the second connection structure 10131, so that both the first ground part 1012 and the second ground part 1013 can be Grounded (GND) through the non-clearance area 11.

Based on the "M-type" bluetooth antenna shown in fig. 3, by designing a symmetrically bent single-fed grounded dipole form, the dipole ground feed point forms an antenna radiator, and the ground forms a radiation isolation wall.

In some embodiments, fig. 4 is a schematic structural diagram of an embodiment of the bluetooth antenna provided in this application, and as shown in fig. 5, when the width L2 of the first ground portion is the same as the width L3 of the second ground portion, the bluetooth antenna may implement the antenna radiation shown in fig. 5.

Fig. 5 is an antenna radiation diagram of the bluetooth antenna provided by the present application, and as fig. 5 shows the radiation direction of the bluetooth antenna shown in fig. 4, it can be seen that the antenna main lobe 21 of the bluetooth antenna is enhanced in the X direction, and the side lobe 22 of the antenna are compressed, and since the width L2 of the first ground part is the same as the width L3 of the second ground part, the radiation direction thereof presents a bilaterally symmetric structure. The isolation full frequency band of the Bluetooth antenna and the Wi-Fi antenna on one side of the Bluetooth antenna obtained according to experimental data at the distance of 20mm can reach 30 Db.

Therefore, the radiation range of the bluetooth antenna provided by the embodiment is narrow, the bluetooth antenna is concentrated in the main lobe direction, when the bluetooth antenna communicates, the interference caused by the Wi-Fi antennas on the two sides is small, the isolation performance of the bluetooth antenna is improved, the interval between the bluetooth antenna and the Wi-Fi antennas on the two sides can be further reduced, and the size of the antenna module is further reduced.

To sum up, the antenna module that this embodiment provided has realized the miniaturized design of product on guaranteeing that bluetooth antenna and both sides Wi-Fi antenna have isolation performance's basis, can enough guarantee antenna module's communication quality, can reduce the antenna module again through the mode that reduces antenna module's size to the occupation of electronic equipment inner space, and then reduce electronic equipment's production design cost.

The embodiment of the present application does not limit the specific implementation of the Wi-Fi antenna, and for example, a miniaturized multi-branch grounded dual-band antenna may be adopted.

In some embodiments, the bluetooth antenna and its antenna radiation as shown in fig. 4 and 5 are only illustrative and may be implemented when the first ground 1012 and the second ground 1013 of the bluetooth antenna 101 as shown in fig. 4 are identical in shape and size. In practical application, the antenna radiation pattern can be changed by adjusting the length and width of the first ground part 1012 and the second ground part 1013.

For example, fig. 6 is a schematic structural diagram of another embodiment of the bluetooth antenna provided in the present application, and as shown in fig. 6, when the width L3 of the second ground part 1013 on the right side of the feeding part 1011 of the bluetooth antenna 101 is increased, the main lobe 21 of the antenna radiation generated by the bluetooth antenna 101 is deviated in a direction away from the second ground part 1013 (i.e., in a direction toward the first ground part 1012). At this time, the bluetooth antenna 101 shown in fig. 6 can be applied to reduce the interference between the bluetooth antenna 101 and the Wi-Fi antenna on the right side thereof without changing the overall layout of the antenna module by increasing the width of the second ground 1013 so that the main lobe 21 of the bluetooth antenna 101 is shifted toward the first ground 1012 thereof (i.e., the left direction in fig. 6) when the bluetooth antenna 101 is closer to the Wi-Fi antenna in the direction of the second ground 1013 (i.e., the right direction in fig. 6).

For another example, fig. 7 is a schematic structural diagram of another embodiment of the bluetooth antenna provided by the present application, and as shown in fig. 7, when the width L2 of the first ground portion 1012 on the left side of the feeding portion 1011 of the bluetooth antenna 101 is increased, the main lobe 21 of the antenna radiation generated by the bluetooth antenna 101 is deviated in a direction away from the first ground portion 1012 (i.e., in a direction toward the second ground portion 1013). At this time, the bluetooth antenna 101 shown in fig. 7 may be applied to reduce interference between the bluetooth antenna 101 and the Wi-Fi antenna on the left side thereof without changing the overall layout of the antenna module by increasing the width of the first ground portion 1012 so that the main lobe 21 of the bluetooth antenna 101 is shifted toward the second ground portion 1013 (i.e., the right direction in fig. 7) when the bluetooth antenna 101 is closer to the Wi-Fi antenna in the direction of the first ground portion 1012 (i.e., the left direction in fig. 7).

In some embodiments, fig. 8 is a schematic structural diagram of another embodiment of the bluetooth antenna provided by the present application, for example, as shown in fig. 8, a height H of a connecting portion 1014 in the bluetooth antenna 101 may be adjusted, and when the height H of the connecting portion 1014 is changed, an operating bandwidth of the bluetooth antenna 101 may be changed, for example, the height H may be adjusted to enable the bluetooth antenna 101 to operate at a bandwidth of 200MHz, and the like.

In some embodiments, the bluetooth antenna may further adjust the isolation between the bluetooth antenna and the Wi-Fi antennas on two sides of the bluetooth antenna by adjusting the length-width ratio and the like. This application does not do the injecive to bluetooth antenna's specific parameters such as height, width, can test and adjust according to operating condition to the realization is to bluetooth antenna radiation direction difference, individualized selection that goes on, makes the bluetooth antenna that this application provided have stronger adaptability, can be applied to in the scene of difference.

Fig. 9 is a schematic structural diagram of another embodiment of the antenna module provided in the present application, where the antenna module shown in fig. 9 further includes, on the basis of the first PCB layer: a second PCB layer. The first PCB layer and the second PCB layer are arranged in parallel, and the first PCB layer may adopt a structure as shown in fig. 3.

In some embodiments, fig. 10 is a schematic structural diagram of a second PCB layer provided in the present application, where the second PCB layer shown in fig. 10 includes a copper-clad portion 20, and an orthogonal projection of the whole bluetooth antenna 101 shown in fig. 3 in the Z direction on the second PCB layer is located in the copper-clad portion 20. In some cases, the area of the copper cladding 20 can just as well comprise a bluetooth antenna.

In some embodiments, in combination with the antenna module shown in fig. 3 and 10, the second end of the first ground part 1012 on the first PCB layer shown in fig. 3 and the second end of the second ground part 1013 each include a plurality of through holes 21, and the copper-clad part on the second PCB layer shown in fig. 10 includes through holes 21 in the same position. So that the first ground part 1012 of the first PCB layer is connected to the copper clad part 20 of the second PCB layer through the through hole 21 and the second ground part 1013 of the first PCB layer is also connected to the copper clad part 20 of the second PCB layer through the through hole 21.

Therefore, the antenna module that this embodiment provided, through the mode on two-layer PCB layer, set up the second PCB layer in the below of the Z direction on first PCB layer as in fig. 9 for the second PCB layer plays the reflection reinforcing effect through the mode that "patch" form back covers copper, further strengthens the radiation intensity of bluetooth antenna on the first PCB layer on the Z direction and the directionality of radiation, reinforcing one-way radiation performance, compression side lobe, thereby the main part radiation of reinforcing antenna.

Exemplarily, when the antenna module shown in fig. 9 is applied to an electronic device such as a television, the television can be hung on a wall surface, the second PCB layer is close to one side of the wall surface for the television, and the first PCB layer is far away from one side of the wall surface for the television, so that the radiation intensity and the directivity of the bluetooth antenna in the Z direction can be improved when the first PCB layer is communicated with the electronic device.

In some embodiments, fig. 11 is a schematic structural diagram of an embodiment of an antenna module provided in the present application, and the antenna module shown in fig. 11 further includes, on the basis of the foregoing embodiment: a communication port 103. The communication port 103 may be disposed in a second clearance area of the first PCB layer, the second clearance area being located on a second edge of the upper side of the first PCB layer, and the first edge and the second edge may be two opposite edges of the rectangular PCB.

In some embodiments, isolation interference exists between the first Wi-Fi antenna and the bluetooth antenna, and between the bluetooth antenna and the second Wi-Fi antenna, so that the antenna module provided by the application can be provided with a decoupling network mode, and isolation interference is reduced to assist in improving isolation. For example, fig. 12 is a schematic structural diagram of an embodiment of the antenna module provided in the present application, and the antenna module shown in fig. 12 is provided with a first decoupling network 107 between the second end of the first Wi-Fi antenna 102A and the second end of the bluetooth antenna 101. The first decoupling network 107 comprises a capacitor C1 and an inductor L1 connected in series. A second decoupling network 108 is arranged between the second end of the bluetooth antenna 101 and the second Wi-Fi antenna 102B, and the second decoupling network 108 comprises a capacitor C2 and an inductor L2 connected in series.

In some embodiments, the essence of decoupling from a network analysis point of view is to drive the mutual impedance of the impedance matrix of the multiport network towards zero, or to drive the back transmission coefficient of the scattering matrix towards zero. Therefore, the introduction of a decoupling network can be divided into the following three steps: in the first step, there is strong coupling between the antennas due to the good impedance match of the initial antennas. Therefore, the three antennas all adopt a grounding mode, and the function of the three antennas is to change the transmission admittance between the two ports from a complex number to a pure imaginary number. And secondly, introducing a shunt reactance to offset the pure imaginary number transmission admittance, so that the value of the transmission admittance is zero, and the decoupling purpose is achieved. And thirdly, due to the introduction of the decoupling network, the impedance of the antenna is mismatched when viewed from the port, and therefore the antenna is matched with the impedance by adding the matching network.

In some embodiments, the magnitudes of C and L in the capacitor C1 and the inductor L1, the capacitor C2 and the inductor L2 may be determined by debugging the vector network analyzer with the goal of zero inter-port transmission admittance of the two antennas on either side of the decoupling network. For example, when C is 2.7pF and L is 5.6nH, the isolation between the bluetooth antenna and the Wi-Fi antenna is about 20dB, and the isolation between the two Wi-Fi antennas is about 15dB, which both meet the requirement of the industry index; meanwhile, the size of the PCB is further reduced, the antenna is placed on the same surface, the radiation of the antenna is facilitated, and the Radiation (RF) performance of the antenna is ensured to be good.

In some embodiments, the second end of each antenna may be connected to an impedance matching circuit, for example, the second end of the bluetooth antenna 101 is further connected to the impedance matching circuit 105 and further connected to the port 202, the second end of the first Wi-Fi antenna 102A is further connected to the impedance matching circuit 104 and further connected to the port 201, and the second end of the second Wi-Fi antenna 102A is further connected to the impedance matching circuit 106 and further connected to the port 203.

In some embodiments, the first decoupling network 107 and the second decoupling network 108 in the antenna module shown in fig. 12 may also be respectively connected in series with a switch unit, when the working performance of the antenna module reaches a preset ideal value, the switch unit may be turned off, and the decoupling processing through the first decoupling network 107 and the second decoupling network 108 may be stopped; when the working performance of the antenna module does not reach the preset ideal value, the decoupling processing is performed by the first decoupling network 107 and/or the second decoupling network 108 by turning on the switch unit.

Finally, it should be noted that: the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present application.
