UHF Near-Field RFID Antenna – 55x20mm

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.

These values describe the antenna’s specified angular coverage in the horizontal and vertical directions. Confirm the measurement convention and antenna orientation with the supplier before using these figures to plan RFID coverage.

Installation direction can affect how the antenna interacts with RFID tags and the surrounding environment. Confirm the intended mounting orientation and test the antenna with the actual reader and tags in the target application.

Confirm that the reader supports the selected frequency band and is compatible with the antenna’s 50 Ω impedance and SMA-female connector. The antenna’s power rating and expected performance should also be checked against the product specifications.
