UHF Near-Field RFID Antenna – 520x380mm

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.

This antenna can be considered for applications requiring localized UHF RFID identification, such as 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.

This antenna operates at 902–928 MHz, has a 50 Ω impedance, and uses an SMA female connector. Ensure that the RFID reader supports the same frequency band and that the connecting cable and RF interfaces are compatible with the installation.

Circular polarization can help reduce sensitivity to tag orientation compared with linear polarization in many RFID applications. However, actual reading performance depends on the tag design, position, distance, and surrounding materials. Testing with the intended tags is recommended.

The 100W maximum power rating indicates the antenna’s stated maximum power-handling capacity. It does not mean that the RFID reader must operate at 100W. The reader’s output power should be configured according to the antenna specifications, the complete RF system, and applicable radio regulations.
