In the related art, each feed source needs to be provided with a feeding point independently, and different feeding points are arranged on different radiators. In the embodiment of the application, the additional feeding points (the feeding points except the first feeding point) and the radiators (the radiators except the first radiator) are not needed to be arranged, so that the common feeding points and the common radiators can be used for receiving and transmitting the radio frequency signals of the first frequency band and the third frequency band, the cost can be reduced, the occupied space of the antenna device (for example, the spring plate assembly can be saved), and the miniaturization arrangement of the antenna device is facilitated.

In the related art, each feed source needs to be provided with a feeding point independently, and different feeding points are arranged on different radiators. In the embodiment of the application, additional feeding points (feeding points except the first feeding point A and the second feeding point B) and radiators (radiating bodies except the first radiating body 111 and the second radiating body 121) are not needed to support the receiving and transmitting of the radio frequency signals of the first frequency band, the common feeding points and the common radiating bodies can be adopted to realize the receiving and transmitting of the radio frequency signals of the first frequency band and the third frequency band, the cost can be reduced, the occupied space of the antenna device (for example, the spring plate assembly can be saved) is reduced, and the miniaturized setting of the antenna device is facilitated.

Wherein the target first variable tone unit 1162 is at least one of the plurality of first variable tone units 1162, and the target second variable tone unit 1172 is at least one of the plurality of second variable tone units 1172.
Based on the second matching circuit 115, the first variable tuning circuit 116 and the second variable tuning circuit 117 provided in the first antenna assembly 110, the antenna device supports a first resonance mode, a second resonance mode, a third resonance mode and a fourth resonance mode, so as to support the receiving and transmitting of radio frequency signals in the third frequency band. It is understood that the first resonant mode, the second resonant mode, the third resonant mode, and the fourth resonant mode are four resonant modes of the first antenna assembly 110 and are generated by the first radiator 111.
The first resonant mode, the second resonant mode, the third resonant mode, and the fourth resonant mode are respectively the fundamental modes corresponding to the first radiator 111 corresponding to the slot 101 from the first ground GND1, as shown in fig. 11. Fig. 11 is a schematic diagram of a return loss curve of the antenna device shown in fig. 7 for receiving and transmitting radio frequency signals in the third frequency band. In fig. 6, the first resonant mode (mode 1), the second resonant mode (mode 2), the third resonant mode (mode 3), and the fourth resonant mode (mode 4) have only one resonant mode at the same time. At least one of the first variable tuning circuit 116 and the second variable tuning circuit 117 may be configured to adjust a shift of a resonance frequency of the third frequency band, for example, by increasing or decreasing the resonance frequency by at least one of the first variable tuning circuit 116 and the second variable tuning circuit 117, so that the resonance frequency when the first antenna assembly 110 may transmit and receive the radio frequency signal of the third frequency band is different. Referring to fig. 11, the resonant frequencies of the third frequency bands corresponding to the mode 1, the mode 2, the mode 3, and the mode 4 are sequentially increased.
It should be noted that, in the embodiment of the present application, the first antenna component 110 includes, but is not limited to, the four resonant modes described above, and by setting the number of tuning paths configured in the first variable tuning circuit 116 and the second variable tuning circuit 117, the first antenna component 110 can support the transmission and reception of radio frequency signals in the frequency band within the bandwidth of 600-1000M of the low frequency band.
In this embodiment, by setting the second matching circuit 115, the first variable frequency circuit 116 and the second variable frequency circuit 117, the resonant frequency of the radio frequency signal in the third frequency band can be adjusted, and the resonant frequency of the resonant mode can be also adjusted, so that the first antenna component 110 can cover part or all of the low frequency band, and obtain higher efficiency in the required frequency band, and the transceiving performance of the low frequency signal can be further improved.

In one embodiment, the fifth resonant mode is a half-wavelength mode of the first radiator 111 corresponding from the first feeding point a to the first ground GND 1. In the LOOP mode, the resonance frequency of the fifth resonance mode can be adjusted by adjusting the resonance parameters of the tuning paths configured in the first variable tuning circuit 116 and the second variable tuning circuit 117. For example, if a variable tuning element having a low resonance parameter (e.g., inductance) is selected as the target variable tuning element, the resonance frequency of the fifth resonance mode shifts toward a high frequency point.
