The IDT 11.5 dBi UHF RFID Circularly Polarized Antenna is a high-gain, long-range antenna engineered for lane-selective and gate-based RAIN RFID applications. Featuring an low axial ratio and a narrow 30° beamwidth, it delivers precise, reliable tag reads even at extended distances and in high-speed environments. Its rugged IP67-rated enclosure and industrial-grade construction make it ideal for outdoor deployments, vehicle identification, and controlled read zones, ensuring stable performance in harsh conditions.
Why Choose the IDT 11.5 dBi UHF RFID Antenna?
Need precise, long-range RFID reading with controlled coverage?
Choose the IDT 11.5 dBi UHF RFID Antenna for targeted, high-performance RFID deployments.
The IDT 11.5 dBi UHF RFID Circularly Polarized Antenna is designed for selective long-range EPC Gen2 / ISO 18000-6C tag reading, offering excellent performance in applications that demand directional control and high read accuracy.Its RHCP (Right-Hand Circular Polarization) combined with an ultra-low axial ratio minimizes polarization mismatch, ensuring dependable tag reads regardless of orientation.
With a focused 30° azimuth beamwidth, high front-to-back ratio, and stable RF characteristics, the antenna enables precise coverage in lanes, gates, and vehicle corridors. Its aluminum reflector and robust ABS/PC radome ensure durability in outdoor and industrial environments, making it a preferred choice for transportation systems, factory automation, and access control solutions.
