corner of the host PCB. When BL600-SA cannot be placed as such, it must be placed on the edge of the
host PCB and the antenna keep out must be observed. An example is shown in
Figure 10: Antenna keep-out area (shown in red), corner of the BL600 development board for BL600-SA module.
Note: 1. BL600 module placed on edge of host PCB.
2. Copper cut-away on all layers in "antenna Keep-out" area under BL600 on host PCB.

6.3.2 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 BL600-SA 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).
