UHF Near-Field RFID Antenna – 400x320mm

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 antenna size depends on the required reading area, tag placement, available installation space, and surrounding materials. This antenna measures 400 × 320 × 6 mm and may suit installations with limited mounting space. Actual reading performance should be evaluated using the intended tags and setup.

Reading stability can be affected by tag orientation, antenna positioning, reader power settings, nearby materials, and the type of RFID tags used. For more consistent results, test the antenna with representative tags under actual operating conditions and adjust the installation based on the results.

Compatibility depends on whether the tags operate in the 902–928 MHz band and suit the intended application. Tag design, mounting surface, orientation, and installation conditions can affect reading performance. Verify the tag specifications and test representative tags before deployment.

Check that the RFID reader supports the 902–928 MHz frequency band and that the RF connection is compatible with the antenna’s SMA female connector. The antenna and reader should also have compatible RF requirements, including impedance and power handling. Use a suitable cable and follow the reader manufacturer’s installation instructions.
