UHF Near-Field RFID Antenna – 900x600mm

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 antenna is available for the 865–868 MHz and 902–928 MHz frequency bands. The appropriate version depends on the RFID reader, tags, and radio regulations in the target market. Make sure the antenna’s frequency band matches the reader and tags used in your application.

A large near-field RFID antenna can be considered for applications that require a defined reading area across a wider surface. Potential applications include item-level inventory, retail product identification, document tracking, and asset management. The final suitability depends on the required reading area, tag placement, and installation conditions.

Circular polarization can help reduce sensitivity to tag orientation compared with linear polarization in many RFID setups. This can be useful when tagged items are not consistently aligned. However, actual reading performance also depends on tag design, placement, distance, and the surrounding environment.

DC Ground indicates that the antenna’s design provides a DC grounding path for its RF structure. This feature is relevant when considering electrical protection in an RFID installation. It should not be treated as a guarantee of complete lightning protection; the overall grounding and surge protection arrangements must be evaluated separately.
