20.5. Antenna free area
To avoid influence and mismatching of the antenna the recommended free area around the
antenna should be maintained. As rule of thumb a minimum distance of metal parts to the
antenna of
λ
/10 should be kept (see figure
). Even though metal parts would influence the
characteristic of the antenna, but the direct influence and matching keep an acceptable level.
