 13www.ibroadlink.com 8.2 Minimizing Radio Interference The following precautions should be considered during designing when using PCB antenna: 1. Do not place any electrical components in antenna area on main board and it’s better to leave this area blank on PCB. 2. It is recommended to not place any electrical components within 10mm range of module antenna and not design any circuit or bond copper on main board under this area. 3. Do not use the module inside any metal case or containers with metal painting. Keep the antenna of wifi module next to the edge of main board during design of PCB to ensure better performance of antenna.
