6.4 Host PCB Layout Recommendations
The ZPM3750 module has an onboard antenna and requires some host PCB layout considerations un-
derneath the module to provide the best RF performance. Refer to Figure 8 for the requirements.
Notes:
1. Due to the surface mount antenna on the module, the area in ‘Zone1’ on all layers of the customer circuit board should be free of
any metal objects. Specifically, there should be no ground plane, traces, or metal shield case.
2. The area in ‘Zone2’ on the top layer of the customer circuit board should have ground only with no signal traces.
