UHF Near-Field RFID Antenna – 600x450mm

A UHF near-field RFID antenna is designed to provide RFID reading and writing within a localized area at close range. It uses near-field electromagnetic coupling to communicate with compatible UHF RFID tags, making it suitable for applications where items need to be identified individually within a defined reading zone. Common applications include item-level inventory, retail product identification, document tracking, and small-item management.

The main difference is how they communicate with RFID tags and how the reading area is designed. Near-field RFID antennas use near-field coupling and are generally suited to close-range identification within a localized area. Far-field RFID antennas rely on radiated electromagnetic waves and are commonly used when tags need to be read over a wider area or at greater distances. The right choice depends on the required reading distance, tag placement, item spacing, and application environment.

This antenna operates in the 902–928 MHz frequency band, has a 50 Ω impedance, and uses an SMA female connector. To ensure compatibility, the RFID reader and connecting cable should support the required frequency band and matching RF interfaces. Regional frequency regulations should also be considered.

Antenna gain is only one factor affecting RFID reading performance. In near-field applications, the goal is often to establish a suitable localized reading area rather than maximize reading distance. The antenna’s design, installation, reader settings, and tag placement all contribute to the final performance, so the antenna should be evaluated in the intended application.

This antenna is specified for indoor use and does not have a stated IP protection rating for outdoor installation. It is therefore intended for indoor applications. If outdoor use is required, confirm the environmental protection requirements with the supplier before installation.

UHF near-field RFID antennas are suitable for applications that require close-range identification within a defined area. Common examples include item-level inventory, retail product identification, document tracking, and small-item management. The antenna should be selected according to the size of the reading area, tag placement, and application requirements.
