4.1 Layout Guide
For optimal performance of the antenna place the module at the outside of the PCB
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. Use good layout practices to avoid any excessive noise coupling to signal lines or supply
voltage lines. Avoid placing plastic or any other dielectric material closer than 5 mm from the
antenna. Any dielectric closer than 5 mm from the antenna will detune the antenna to lower
frequencies.
