UHF Near-Field RFID Antenna – 320x320mm

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.

Its 320 × 320 × 6 mm form factor may suit fixed RFID installations where the available mounting area accommodates the antenna. Application suitability depends on the required reading zone, tag placement, reader configuration, and installation environment.

Check that your RFID reader supports the 902–928 MHz band and is compatible with the antenna’s 50 Ω impedance and SMA-female connector. Also confirm that the reader’s output power is within the antenna’s 100 W maximum power rating.

Circular polarization can help accommodate variations in tag orientation compared with linear polarization. Actual reading performance still depends on tag characteristics, antenna placement, reader settings, and the surrounding environment.

DC Ground is a specified feature of the antenna’s lightning protection design. The overall protection depends on the grounding arrangement and installation, so confirm the required grounding and surge protection before deployment.
