Figure 4: Module mounting example
- Please do not place any metal components in gray shaded space(*1), such as signal line and metal
chassis as possible except for main board while mounting the components in *1 space on the main
board is allowed except for no copper plating area(*2).
- (*2)This area is routing prohibited area on the main board and it includes on board antenna
routing prohibited area the size can refer to mechanical drawing shaded space . Please do not
place copper on any layer.
- (*3) Characteristics may deteriorate when GND pattern length is less than 30mm. It should be 30
mm or more as possible.
