Module mounting considerations
Good RF layout practice should be observed. In particular, any ground return required by the antenna
or feed should be connected directly to the RF GND pins at the antenna end of the module, and not to
the OV pins which are intended as DC grounds only. All connecting tracks should be kept as short as
possible to avoid any problems with stray RF pickup.
If the connection between module and antenna does not form part of the antenna itself, it should be
made using 50Ω microstrip line or coax or a combination of both. It is desirable (but not essential) to fill
all unused PCB area around the module with ground plane.
