WA500W301151 Datasheet, PDF (2/20 Pages) List of Unclassifed Manufacturers – Stingray Adhesive Mount Wi-Fi/Zigbee Antenna

1. Introduction
The WA.500w Stingray is a high efficiency, high gain adhesive mount dual band wireless
antenna. Its high quality low profile covert housing can be attached onto the glass or
plastic. The WA.500w is designed for applications that require omni-directional gain
across both bands to ensure wide coverage area and constant reception and transmission
for Wi-Fi and ZigBee applications.
Many module manufacturers specify peak gain limits for any antennas that are to be
connected to that module. Those peak gain limits are based on free-space conditions. In
practice, the peak gain of an antenna tested in free-space can degrade by at least 1 or
2dBi when put inside a device. So ideally you should go for a slightly higher peak gain
antenna than mentioned on the module specification to compensate for this effect, giving
you better performance.
Upon testing of any of our antennas with your device and a selection of appropriate
layout, integration technique, or cable, Taoglas can make sure any of our antennas’ peak
gain will be below the peak gain limits. Taoglas can then issue a specification and/or
report for the selected antenna in your device that will clearly show it complying with the
peak gain limits, so you can be assured you are meeting regulatory requirements for that
module.
For example, a module manufacturer may state that the antenna must have less than
2dBi peak gain, but you don’t need to select an embedded antenna that has a peak gain
