AN440 RFID Antenna


The AN440 is a robust, high-performance UHF RFID antenna with a wide read field and dual-element design. It is built for demanding, high-throughput environments — suitable for both indoor and outdoor use — where you need reliable reads over large areas (warehouses, docks, gates, portals, etc.).

The AN440 RFID antenna delivers strong, consistent RFID tag reads across large zones, even under heavy traffic or dense product conditions. Its dual-element design (with both left- and right-hand circular polarizations) gives flexibility and improved tag detection regardless of tag orientation — which boosts read reliability for mixed loads, pallets, cartons, or items in metal/liquid-rich environments.

Thanks to its rugged housing (with high environmental protection), AN440 can be mounted on walls or ceilings, indoors or outdoors. It’s well-suited for creating read zones around warehouse doorways, dock doors, conveyor belts, storage racks, or anywhere goods and pallets move in and out. Its design supports use as a bi-static antenna (dual-element) or as two independent mono-static antennas — giving flexibility depending on your installation needs.

Overall, AN440 offers a balance of range, coverage, durability, and flexibility — making it a strong general-purpose antenna for logistics, warehousing, retail back-rooms, manufacturing, and any high-throughput RFID deployment.
