UHF Near-Field RFID Antenna – 220x220mm

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 right frequency version depends on your RFID reader, tags, and installation location. Confirm that the antenna frequency matches your reader and tags and complies with local frequency regulations.

The beamwidth describes the antenna’s angular radiation coverage in the horizontal and vertical directions. The 66° × 65° beamwidth helps characterize its coverage pattern, while the actual RFID reading area also depends on tag position, reader settings, and the installation environment.

Its compact 220 × 220 × 5 mm design can help fit RFID systems into workstations, counters, or equipment with limited mounting space. Check the available installation area, cable routing, and nearby materials before integration.

The front-to-back ratio compares radiation in the antenna’s forward direction with radiation in the opposite direction. A higher ratio indicates stronger forward radiation relative to the rear, which may be useful when planning antenna placement and reducing unwanted rearward coverage.
