UHF Near-Field RFID Antenna – 270x270mm

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.

The appropriate frequency band depends on the RFID reader, tags, and radio regulations in your target market. Before ordering, confirm that the selected antenna version matches your reader and tags and complies with the frequency requirements for your installation location.

Beamwidth describes the angular coverage of an antenna’s main radiation pattern. The specified 58° horizontal and 58° vertical beamwidths help characterize its directional behavior. However, beamwidth alone does not determine the actual RFID reading area, which also depends on antenna design, tag characteristics, reader settings, and installation conditions.

The antenna measures 270 × 270 × 1 mm, making its slim profile potentially useful for installations with limited mounting depth. Integration depends on the mounting arrangement, nearby materials, cable routing, and required reading area. Test the antenna with the intended tags and installation setup before finalizing the design.

This antenna is specified for indoor use, with an operating temperature range of -20°C to +60°C. Its specifications do not provide an IP protection rating for outdoor exposure. If outdoor installation is required, confirm the necessary environmental protection before selecting an antenna.
