UHF Near-Field RFID Antenna – 210x170mm

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 correct frequency version depends on your RFID reader, tags, and installation location. Confirm frequency compatibility with your reader and tags, and check the applicable local regulations before selecting a version.

With a thickness of just 1.5 mm, this antenna can be considered for RFID systems with limited installation depth, such as compact equipment or integrated work surfaces. The mounting method, cable routing, and nearby materials should be checked before installation.

Antenna gain describes how radio energy is distributed relative to a reference antenna. A gain of -6 dBi alone does not determine reading distance or accuracy; actual performance depends on the reader, tags, antenna placement, and surrounding environment.

Its circular polarization can help read tags with different orientations compared with a linearly polarized antenna, depending on the setup. Tag placement, antenna position, and the surrounding environment can still affect reading performance.
