Miniaturization and low cost are achieved through the structural design of the resonant cavity 10 and the first conductive part 201, the gap unit 203 and the second conductive part 202. Please combine Figure 5 and Figure 6 , Figure 5 is a signal coverage diagram of the antenna module 100, Figure 6 : is an efficiency diagram of the antenna module 100. The slot unit 203 of the slot unit 203 achieves multi-band coverage of 2.4 GHz, 5 GHz and 6 GHz frequency bands, and has efficient antenna performance and strong portability. Specifically, the signal can be fed from the slot unit 203 through the resonant cavity 10, and the resonant frequency of the resonant cavity 10 can be tuned by adjusting the length of the slot unit 203.
