5. Antenna Information Antenna Type PCB board antenna Reduce Antenna Interference While using the On-board PCB antenna, in order to have the best Wi-Fi performance, it’s recommended to keep a minimum15mm distance between the antenna part and the other metal pieces. Fig. 1 shows five common antenna placement modes, of which scheme 1 and scheme 2 have the best performance, and have little influence on the RF performance, which is comparable to the RF performance tested by the module alone.
