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; note also the small secondary keep-out area which
is required for best performance using the -PA version. If using the U.FL RF connector the “keep-
out” area can be significantly reduced.
