3 Confidex Viking™ beacon radiation efficiency
Picture below shows Confidex Viking™ beacon radiation patterns on three different attachment
materials. Radiation patterns, pictured below, conform to how the PCB is placed inside beacon,
approximately in a 45° angle. Radiation efficiency changes when attaching beacon to certain
materials. Listed below are directional radiation measurements done for Confidex Viking™ beacon
taken in two orientations, from azimuth 0° angle and in 90° elevation.
Best radiation efficiency is always towards the front of the beacon. In the middle of tag, diagonally,
there are two segments that radiate with lesser efficiency. This can mean worse than normal read
range distance in some spots depending on how Confidex Viking™ beacons are placed.
Radiation pattern measurements in Azimuth 0° angle.
Radiation pattern measurements in 90° elevation angle.
Because board orientation is not specified in production, radiation pattern can be mirrored in practice.
If your positioning system has gateways or readers, please take beacon orientation into consideration
to ensure best performance.
