5. Antenna
The WAT2 Module includes an integrated PCB trace antenna. The PCB antenna employs a
meandering F-antenna design that is very compact and supports omni-directional signal
radiation. To maximize the antenna efficiency an adequate ground should be provided on the
base board. The position of the module on the base board and overall design of the product
enclosure contributes to the antenna’s performance.
Here are some guidelines to help ensure antenna performance:
 Keep all copper (planes and traces) away form the antenna portion of the module
 Keep the antenna away from metal parts (i.e. enclosures, large heat sinks, etc…)
 Keep internal wiring and other components away from the Antenna
 Do not place the antenna inside a metal enclosure
 Keep plastic enclosures ½ in. or more from the antenna
