ZS-C12-L445 UHF 12dBi RFID Circularly Polarized Antenna

The ZS-C12-L445 12dBi UHF RFID circularly polarized antenna features high gain and a low standing wave ratio (SWR). Its circularly polarized radiation design ensures stable activation of UHF RFID tags regardless of their orientation as they enter the field—eliminating the strict alignment requirements associated with linearly polarized antennas. This makes it particularly well-suited for applications involving pallets, totes, vehicles, or assets where tag orientation may be random. When paired with standard 4-port or 8-port UHF RFID fixed readers, it enables the rapid deployment of long-range identification points, such as those used in warehouse portals, vehicle lanes, and loading dock entry/exit points.
