The working principle of the antenna assembly provided by the embodiment of the application is that when no human hand approaches, the capacitance value sensed by the first sensor module 533 and the second sensor module 534 is C0, when the electronic device is in a medium-frequency or high-frequency state, and when the human hand holds any antenna (such as the third antenna or the fifth antenna) containing medium-high frequency or high-frequency, the capacitance value sensed by the first sensor module 533 or the second sensor module 534 is CX, and when the received capacitance change value CX-C0 reaches a preset threshold value, the control switch 52 switches the medium-high frequency antenna to the third antenna or the fifth antenna.
Specifically, the bodies of the third antenna and the fifth antenna are used as sensors and are electrically connected to the first sensor module 533 and the second sensor module 534, respectively, and the first sensor module 533 and the second sensor module 534 are electrically connected to the baseband module 532 for transmitting the received capacitance to the baseband module 532. The baseband module 532 is electrically connected to the rf module 531 for controlling the control switch 52. The control switch 52 is used to control switching of the medium and high frequency antennas to the third antenna or the fifth antenna.
For example, the present embodiment may switch the default mid-high frequency antenna in the original free space to the third antenna, i.e., the control switch 52 turns on the port1, and when the user holds the third antenna with the left hand and the right hand, respectively, the capacitance values sensed by the third antenna are C3 and C3 ', respectively, and the value of C3' -C0, i.e., the variation of the capacitance value, is set as the threshold value for switching the control switch 52 from the port1 to the port2, because the influence of the hand on the third antenna is greater when the user holds the bottom of the electronic device with the right hand. In practical use, when the first sensor module 533 detects that the value of C3' -C0 reaches the threshold value, the middle-high frequency antenna is switched from the third antenna to the fifth antenna by controlling the switch 52.
Similarly, when the middle and high frequency antenna is switched to the fifth antenna, the control switch 52 turns on the port 2. The capacitance values sensed by the fifth antenna are C5 and C5 'when the user holds the fifth antenna with the left and right hands, respectively, and the values of C5-C0, i.e., the amount of change in the capacitance values, are set as the threshold for controlling the switch 52 to switch from port2 to port1, because the effect of the hand on the fifth antenna is greater when the user's left hand holds the bottom of the electronic device. In practical use, when the second sensor module 534 detects that the value of C5-C0 reaches the threshold value, the middle and high frequency antennas are switched from the fifth antenna to the third antenna by the control switch 52.
In one embodiment, if the current capacitance variation value reaches the corresponding threshold value when both the first sensor module 533 and the second sensor module 534 sense, the middle-high frequency antenna may be fixedly disposed on the third antenna or the fifth antenna. For example, when holding the bottom of the electronic device with both hands, the best antenna performance or the best antenna performance in free space is selected.
