The antenna assembly 10 includes a first antenna 110 . The first antenna 110 includes a first radiator 111 , a first signal source 112 , and a band pass filter (Band Pass Filter, BPF) 114 . The first radiator 111 includes a first ground end G1 and a first free end F1, and a first feed point P1 and a connection point P3 are disposed between the first ground end G1 and the first free end F1. The first ground terminal G1 is connected to the ground electrode GND2, 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 still connected The point P3 is electrically connected to the band-pass filter circuit 114 to the ground GND1. 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 resonant mode, and the first resonant mode The resonant current of the state is distributed between the first ground terminal G1 and the first free terminal F1.

本申请中，带通滤波电路114应用于天线组件10时，用于调谐第一辐射体111的电长度，以使第一辐射体111至少产生第一谐振模态和第二谐振模态。本申请对于带通滤波电路114连接第一辐射体111的位置不做具体的限定。In the present application, when the bandpass filter circuit 114 is applied to the antenna assembly 10 , it is used to tune the electrical length of the first radiator 111 , so that the first radiator 111 generates at least the first resonance mode and the second resonance mode.

相关技术中，由于天线辐射体长度与天线所支持的频段相对应，由于天线辐射体长度的限制，所述第一天线110仅仅能够收发第一频段的电磁波信号，而不支持第二频段的电磁波信号，或者，所述第一天线110仅仅能够收发第二频段的电磁波信号，而不支持第一频段的电磁波信号。举例而言，当第一频段为GPS-L5频段，第二频段为GPS-L1频段时，假设第一辐射体111的物理长度为支持GPS-L1频段的产物，而要使得在GPS-L5频段产生谐振的辐射体物理长度大于第一辐射体111的物理长度，换言之，第一辐射体111的物理长度不够支持GPS-L1频段。In the related art, since the length of the antenna radiator corresponds to the frequency band supported by the antenna, and due to the limitation of the length of the antenna radiator, the first antenna 110 can only transmit and receive electromagnetic wave signals in the first frequency band, but does not support electromagnetic waves in the second frequency band. signal, or, the first antenna 110 can only transmit and receive electromagnetic wave signals in the second frequency band, but does not support electromagnetic wave signals in the first frequency band. For example, when the first frequency band is the GPS-L5 frequency band and the second frequency band is the GPS-L1 frequency band, it is assumed that the physical length of the first radiator 111 is a product that supports the GPS-L1 frequency band, and the GPS-L5 frequency band is The physical length of the radiator that generates the resonance is greater than the physical length of the first radiator 111 , in other words, the physical length of the first radiator 111 is not enough to support the GPS-L1 frequency band.

若需要同时支持第一频段和第二频段的电磁波信号，则需要额外设置一个天线支持第二频段或第一频段的电磁波信号。由此可见，相关技术中需要支持第一频段的电磁波信号以及第二频段的电磁波信号需要较多的天线，从而导致天线组件10的体积较大，占用的空间较大。由于相关技术中天线组件10的体积较大，占用的空间较大，当相关技术中的天线组件10应用于电子设备1中时与电子设备1中的其他器件的堆叠难度较大。此外，相关技术中，所述第一天线110仅仅能够收发第一频段的电磁波信号，需要额外设置一个天线支持第二频段的电磁波信号，可导致所述天线组件10中的射频链路插损增加。此外，相关技术中，设置支持第一频段的电磁波信号的天线以及再设置额外的天线支持第二频段的电磁波信号可导致所述天线组件10的成本较高。If the electromagnetic wave signals of the first frequency band and the second frequency band need to be supported at the same time, an additional antenna needs to be set up to support the electromagnetic wave signals of the second frequency band or the first frequency band. 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 .

本实施方式中的天线组件10中通过增加带通滤波电路114，可使得第一天线110可支持第一频段的电磁波信号及第二频段的电磁波信号，无需额外设置天线来支持第二频段的电磁波信号，因此，所述天线组件10的体积较小，占用的空间不大。当本实施方式中的天线组件10应用于电子设备1中与电子设备1中的其他器件堆叠时，堆叠难度较低。此外，本实施方式中的天线组件10第一天线110可支持第一频段的电磁波信号及第二频段的电磁波信号，因此，天线组件10中的射频链路插损较小。此外，本实施方式中的天线组件10第一天线110可支持第一频段的电磁波信号及第二频段的电磁波信号可降低所述天线组件10的成本。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 of the antenna assembly 10 in this embodiment can support electromagnetic wave signals of the first frequency band and electromagnetic wave signals of 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 .
