5.1 PCB Design Guidelines

For optimal performance of the BGM111, please follow the following guidelines:

• Place the module at the edge of the PCB as shown in the the figure below.

• Do not place any metal (traces, components, battery etc.) within the clearance area of the antenna.

• Connect all the GND pins directly to a solid GND plane.

• Place the GND vias as close to the GND pins as possible.

• Do not place plastic or any other dielectric material in touch with the antenna.
