UHF Near-Field RFID Antenna – 50x50mm

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 50 × 50 × 1 mm footprint may suit RFID devices with very limited installation space. Before integration, check the mounting area, connector clearance, cable routing, and the antenna’s intended operating conditions.

These values describe the antenna’s specified angular radiation pattern in the horizontal and vertical directions. They help characterize its coverage, but the actual RFID reading area depends on tag characteristics, reader settings, installation orientation, and the surrounding environment.

VSWR indicates how well the antenna is matched to its feed line at the operating frequency. A VSWR of 1.2 or lower indicates a good impedance match under the specified conditions, but it does not by itself guarantee a particular reading distance or accuracy.
