Figure 9: Antenna keepout on DVK-RM1xx PCB (shown in red) with RM1xx module placed near the corner.
Note: 1. RM1xx module placed on edge of host PCB (close to the corner of the PCB).
2. Copper cut-away on all layers in “antenna Keep-out” for a host PCB.
5.2.2 Antenna Keep-out and Proximity to Metal or Plastic
Checklist (for metal /plastic enclosure):
Minimum safe distance for metals without seriously compromising the antenna (tuning) is 40mm top/bottom and
30mm left or right.
Metal close to the RM1xx chip monopole antenna (bottom, top, left, right, any direction) will have degradation on the
antenna performance. How much; that is entirely system dependent which means some testing by customer required
(in their host application).
Anything metal closer than 20mm will start to significantly degrade performance (S11, gain, radiation efficiency).
It is best that the customer tests the Range with mock-up (or actual prototype) of the product to assess effects of
enclosure height (and material whether metal or plastic).
