XBee® Wi-Fi RF Modules

Antennas should reside above or away from any metal objects like batteries, tall

electrolytic capacitors or metal enclosures. Antenna elements radiate perpendicular to

the direction they point. Thus a vertical antenna emits across the horizon.

PCB Antennas should not have any ground planes or metal objects above or below the

module at the antenna location. For best results, the module should be in a plastic

enclosure instead of a metal one. It should be placed at the edge of the PCB to which it

is mounted. The ground, power and signal planes should be vacant immediately below

the antenna section. The following drawing shows the recommended PCB keepout area

for XBee embedded antennas.
