When the antenna device is connected to the APs such as the multi-antenna route in a butt joint mode, and when a user needs WiFi high-speed service, software setting is carried out, the main antenna is switched to the BAW1 through the DPDT2, and the diversity antenna is switched to the BAW2 through the DPDT 2.

During downlink service, the WiFi data stream of the AP can be received through the main antenna, the diversity antenna, and the WBG antenna at the same time, and through the BAW1, the BAW2, and the BAW3, respectively, a useful signal of 2.4G/5G frequency is screened out, and then enters the WBG transceiver, power amplification is performed through an LNA2 built In the WBG transceiver, and finally enters the main chip for signal processing and upper layer display, thereby achieving the effect of Multiple-path parallel reception (Multiple In).

During uplink service, the main chip sends Out a data signal, the data signal is subjected to power amplification through a PA2 built in the WBG transceiver, and then the data signal correspondingly reaches the main antenna, the diversity antenna and the WBG antenna through the BAW1, the BAW2 and the BAW3, is radiated and sent at the same time, and finally reaches an AP end (that is, data stream is opposite to downlink service), so that an effect of Multiple-path concurrence (Multiple Out) is achieved.
