Near Field RFID Antenna – 230x230mm

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.

With a 230 × 230 mm footprint and a thickness of just 6 mm, this antenna can be integrated into RFID equipment and workstations where installation space is limited. Check the available mounting area before installation.

Circular polarization helps read RFID tags in different orientations, reducing the need to align each tag with a specific linear polarization direction. Actual reading performance depends on tag design, placement, and the surrounding environment.

The antenna uses a DC Ground design as part of its lightning-protection approach. For installations exposed to lightning or electrical surges, the overall grounding and protection system should be designed according to the site requirements.

The antenna has an operating temperature range of -20°C to 60°C. Confirm that the installation environment remains within this range and check other environmental requirements before choosing it for a specific application.
