For ideal RF performance when using the on-board antenna, the antenna should be located at the corner
of the carrier PCB. There should be no components, tracks or copper planes in the Keep-out area which
should be as large as possible.
When placing the module please either locate the antenna in the corner edge of PCB. So that the
recommended antenna keep out zone is being followed, or add a no copper zone as mentioned keep out
area.
