Near Field RFID Antenna – 150x100mm

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.

Its small footprint and 6 mm thickness make it a potential option for compact RFID devices and embedded systems. Confirm that the available mounting space, connector access, and operating frequency meet your design requirements.

The antenna uses a 50 Ω impedance and an SMA-Female connector, with a maximum power rating of 100 W. Check connector compatibility, impedance matching, and the reader’s RF output specifications before connecting it.

The antenna features a DC Ground design for its lightning-protection approach. For installations exposed to electrical surges, confirm the grounding requirements and whether additional protection is needed for the complete system.

Measuring 150 × 100 × 6 mm and weighing only 0.12 kg net, this antenna is suitable for RFID equipment and installations where space and weight need to be considered.
