For example, the antenna signals include antenna signals of two frequency bands of N77(3.3 to 4.2GHz) and N79(4.8GHz to 5GHz), 4 signal sources simultaneously transmit antenna signals of an N77 frequency band, and 4 frequency band switching modules adjust internal circuits of the signal sources, so that the corresponding antenna structures transmit the antenna signals of the N78 frequency band. When the antenna signal of the N79 frequency band needs to be transmitted, 4 signal sources transmit the antenna signal of the N79 frequency band at the same time, and the 4 frequency band switching modules adjust the internal circuits thereof, so that the antenna signal of the N79 frequency band is transmitted by the corresponding antenna structure. Therefore, the antenna signal transmission and reception of the two frequency bands can be realized without additionally arranging more antenna structures.
It should be noted that, according to the requirement of the antenna signal frequency band, the frequency band switching module may include a plurality of adjusting circuits. For example, the antenna signal includes antenna signals of three frequency bands, and the frequency band switching module includes three adjusted circuits, which correspond to the antenna signals of one frequency band, respectively.
