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).
