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.
Key Features & Benefits
· 12dBi High Gain & 40° Narrow Beam: Concentrates energy for long-distance reading and accurate zone control.
· Superior ≥22 dB Front-to-Back Ratio: Minimizes rear-read interference, making it ideal for toll booths and adjacent parking lanes.
· Heavy-Duty Large Panel Design: Features a robust aluminum reflector and UV-resistant ABS radome for long-term outdoor durability.
· Weather & Wind Resistant: Withstands wind speeds up to 36.9 m/s (effective wind loading area ≤0.2 m²).
· Circular Polarization: Reliable reads regardless of tag orientation.
· Versatile Mounting: Bottom-exit N-Female connector and a mounting bracket compatible with Ø40–Ø80 mm poles.
Applications
