Data Sheet

Placement of metal parts
 Minimum safe distance for metal parts without seriously compromising the
antenna (tuning) is 40 mm top/bottom and 30 mm left or right.
 Metal close to the module antenna (bottom, top, left, right, any direction) will
have degradation on the antenna performance. The amount of that degradation
is entirely system dependent, meaning you will need to perform some testing
with your host application.
 Any metal closer than 20 mm will begin to significantly degrade performance
(S11, gain, radiation efficiency).
 It is best that you test the range with a mock-up (or actual prototype) of the
product to assess effects of enclosure height (and materials, whether
metal or plastic).
