The first radiator 111 and the second radiator 121 are spaced apart and coupled to each other, that is, the first radiator 111 and the second radiator 121 have the same aperture. Due to the coupling effect of the second radiator 121, the first antenna 110 not only uses the first radiator 111 to send and receive electromagnetic wave signals, but also uses the second radiator 121 to send and receive electromagnetic wave signals, so that the first antenna 110 can work in a wider frequency band. Similarly, the second antenna 120 can not only use the second radiator 121 to send and receive electromagnetic wave signals, but also use the first radiator 111 to send and receive electromagnetic wave signals, so that the second antenna 120 can work in a wider frequency band. In addition, because the first antenna 110 can use not only the first radiator 111 but also the second radiator 121 to send and receive electromagnetic wave signals when working, the second antenna 120 can use not only the second radiator 121 but also the second radiator 121 when working.

Correspondingly, when the third antenna 130 in the second antenna module 10b is blocked, the first antenna 110 in the first antenna module 10a may not be blocked. Therefore, the first antenna module can be used The first antenna 110 in the group 10a is used to send and receive electromagnetic wave signals, thereby ensuring the communication function of the antenna assembly 10 . Likewise, since the first antenna module 10a and the second antenna module 10b are spaced apart, when the second antenna 120 in the first antenna module 10a is blocked, the second antenna The fourth antenna 140 in the module 10b may not be blocked. Therefore, the fourth antenna 140 in the second antenna module 10b can be used to send and receive electromagnetic wave signals, thereby ensuring the communication function of the antenna assembly 10 . Correspondingly, when the fourth antenna 140 in the second antenna module 10b is blocked, the second antenna 120 in the first antenna module 10a may not be blocked. Therefore, the first antenna module can be used The second antenna 120 in the group 10a is used to send and receive electromagnetic wave signals, thereby ensuring the communication function of the antenna assembly 10 .

The detection unit 710 is used for detecting whether the first antenna 110 and the second antenna 120 in the first antenna module 10a are blocked, and is also used for detecting the third antenna 130 in the second antenna module 10b and whether the fourth antenna 140 is blocked. When the first antenna 110 in the first antenna module 10a is blocked, the control unit 720 turns off the first antenna 110 in the first antenna module 10a and turns on the second antenna module 10b The third antenna 130 in , wherein the third antenna 130 is not blocked; when the second antenna 120 in the first antenna module 10a is blocked, the control unit 720 turns off the first antenna The second antenna 120 in the module 10a and the fourth antenna 140 in the second antenna module 10b are turned on, wherein the fourth antenna 140 is not blocked.

In one embodiment, the detection unit 710 is configured to detect the signal strengths of the first antenna 110 , the second antenna 120 , the third antenna 130 , and the fourth antenna 140 .

Similarly, when the strength of the electromagnetic wave signal received and received by the third antenna 130 attenuates to a third threshold, the third antenna 130 is considered to be blocked; when the strength of the electromagnetic wave signal received and received by the fourth antenna 140 is attenuated to For the third threshold, it is considered that the fourth antenna 140 is blocked. Wherein, the first threshold value may be the same as the third threshold value, or may be different. The second threshold may be the same as or different from the fourth threshold. The first threshold value may be the same as or different from the second threshold value. For the convenience of detection, in this embodiment, the first threshold is equal to the second threshold, the third threshold is equal to the fourth threshold, and is equal to a preset threshold. In other words, in an embodiment, when the detection unit 710 detects that the signal strength of any antenna is less than or equal to the preset threshold, the control unit 720 determines that the signal strength is less than or equal to the preset threshold. The antenna with the threshold is blocked; when the detection unit 710 detects that the signal strength of any antenna is greater than the preset threshold, the control unit 720 determines that the antenna with the signal strength greater than the preset threshold is not occlude.

Similarly, the detection unit 710 is further configured to detect whether the third antenna 130 in the second antenna module 10b is blocked. When the third antenna 130 is blocked, the control unit 720 turns on the third antenna 130 The unobstructed first antenna 110 in the antenna module 10a ensures that the antenna assembly 10 can still transmit and receive electromagnetic wave signals that the first antenna 110 and the third antenna 130 can transmit and receive. When the fourth antenna 140 in the second antenna module 10b is blocked, the control unit 720 turns on the unblocked second antenna 120 in the first antenna module 10a, so as to ensure the antenna The component 10 can still transmit and receive electromagnetic wave signals that the second antenna 120 and the fourth antenna 140 can transmit and receive.

In this embodiment, in addition to the first radiator 111 , the first antenna 110 further includes a first signal source 112 and a band-pass filter circuit 114 . The first radiator 111 includes a first ground end G1 and a first free end F1. A first feeding point P1 and a connecting point P3 are disposed between the first grounding end G1 and the first free end F1. The first radiator 111 is electrically connected to the first signal source 112 at the first feeding point P1, and the first radiator 111 is also electrically connected to the bandpass filter circuit 114 at the connection point P3 to the ground. The first signal source 112 is used to provide an excitation signal of a first frequency band, and the excitation signal of the first frequency band is used to excite the first radiator 111 to generate a first resonance mode (see the mode in FIG. 28 ). b). The first signal source 112 is also used to provide an excitation signal of a second frequency band, and the excitation signal of the second frequency band is used to excite the first radiator 111 to generate a second resonance mode (see mode a in FIG. 28 ). ), wherein the first frequency band includes the GPS-L1 frequency band, and the second frequency band includes the GPS-L5 frequency band.

When the first radiator 111 is electrically connected to the band-pass filter circuit 114 , the first antenna 110 transmits and receives electromagnetic wave signals of a first frequency band, and can also receive and transmit electromagnetic wave signals of a second frequency band, wherein the first frequency band and the The second frequency bands are different. When the first radiator 111 is disconnected from the bandpass filter circuit 114 , the first antenna 110 can transmit and receive electromagnetic wave signals in the first frequency band, but cannot transmit and receive electromagnetic wave signals in the second frequency band. It can be seen that, due to the addition of the band-pass filter circuit 114, the first antenna 110 can transmit and receive electromagnetic wave signals of the second frequency band that cannot be transmitted and received originally, so that the antenna assembly 10 can transmit and receive electromagnetic wave signals of more frequency bands. , thereby improving the communication performance of the antenna assembly 10 .

In this embodiment, the first frequency band is the GPS-L1 frequency band (the resonant frequency is 1575 MHz), and the second frequency band is the GPS-L5 frequency band (the resonant frequency is 1176 MHz). It can be understood that, in other implementation manners, the first frequency band and the second frequency band may also be other frequency bands different from the GPS-L1 frequency band and the GPS-L5 frequency band.

In the related art, the first antenna 110 can only transmit and receive electromagnetic wave signals in the first frequency band, but does not support electromagnetic wave signals in the second frequency band. If it needs to support electromagnetic wave signals in the second frequency band, an additional antenna needs to be set up to support the second frequency band. electromagnetic wave signal. It can be seen that in the related art, more antennas are required to support the electromagnetic wave signal of the first frequency band and the electromagnetic wave signal of the second frequency band, resulting in a larger volume of the antenna assembly 10 and a larger space occupied. Since the antenna assembly 10 in the related art has a large volume and occupies a large space, when the antenna assembly 10 in the related art is applied in the electronic device 1 , it is difficult to stack with other devices in the electronic device 1 . In addition, in the related art, the first antenna 110 can only transmit and receive electromagnetic wave signals of the first frequency band, and an additional antenna needs to be set up to support the electromagnetic wave signals of the second frequency band, which may increase the insertion loss of the radio frequency link in the antenna assembly 10 . In addition, in the related art, disposing an antenna supporting the electromagnetic wave signal of the first frequency band and disposing an additional antenna to support the electromagnetic wave signal of the second frequency band may result in higher cost of the antenna assembly 10 .

By adding a band-pass filter circuit 114 to the antenna assembly 10 in this embodiment, the first antenna 110 can support the electromagnetic wave signal of the first frequency band and the electromagnetic wave signal of the second frequency band, and no additional antenna is required to support the electromagnetic wave of the second frequency band Therefore, the volume of the antenna assembly 10 is small and takes up little space. When the antenna assembly 10 in this embodiment is applied in the electronic device 1 to be stacked with other devices in the electronic device 1 , the stacking difficulty is low. In addition, the first antenna 110 in the antenna assembly 10 in this embodiment can support electromagnetic wave signals in the first frequency band and electromagnetic wave signals in the second frequency band, so the insertion loss of the radio frequency link in the antenna assembly 10 is relatively small. In addition, the first antenna 110 of the antenna assembly 10 in this embodiment can support the electromagnetic wave signal of the first frequency band and the electromagnetic wave signal of the second frequency band, which can reduce the cost of the antenna assembly 10 .
