UHF Near-Field RFID Antenna – 130x130mm

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 and check local regulations before selecting the antenna.

Its compact 130 × 130 × 6 mm design can be considered for RFID equipment with limited mounting space. Check the available installation area, cable routing, and required reading zone to determine whether it fits your application.

A 0 dBi gain rating describes the antenna’s gain relative to an ideal isotropic reference. It does not determine reading distance on its own; actual performance depends on the reader, tags, antenna placement, and surrounding environment.

Confirm that the reader supports the selected frequency band and is compatible with the antenna’s 50 Ω impedance and SMA-female connector. Also check the reader’s power output against the antenna’s maximum power rating of 100 W.
