When selecting PCB antenna, the following points should be paid attention to when placing

the module:

1. Users can't place components and pave the floor in the area corresponding to PCB base plate

and module antenna. It's better to hollow out the PCB in this area.

2. It is suggested that no components should be placed within 30mm of the module antenna area,

and the wiring of the module bottom plate should be avoided as far as possible in this area, and

copper deposition is prohibited.

3. Do not place the module in the metal shell or the mold with metal spray paint.

4. It is strongly recommended that the antenna of the WiFi module should be close to the edge of

the bottom plate as far as possible in PCB layout, as shown in the figure below, so as to ensure

the good performance of the antenna.
