RFID Antennas

A critical component of any RFID system is the antenna system being deployed. Antennas grab the RF signal and send them to the readers for their translation into useable data. The higher the antenna gain, the larger the read range becomes. However, higher gain is not always better.

Having a controlled read range is crucial to the operational use of RFID. Choosing the correct antenna, with the best RFID pattern to match the application is very important, but mechanical characteristics must also be considered. Antenna size, mounting options, and IP ratings for outdoor installations need to be analyzed for each read zone.
