5.5dBi UHF RFID Patch Antenna – 140x120mm

An RFID antenna transmits and receives radio frequency signals between an RFID reader and RFID tags. It enables the reader to communicate with tags and retrieve their stored identification data. In a typical RFID system, the antenna works with the reader, tags, and software to support functions such as inventory tracking, asset identification, and access control. Antenna selection affects the reading area, communication performance, and reliability of the overall RFID system.

Circularly polarized RFID antennas are useful when tag orientations vary or cannot be controlled, while linearly polarized antennas generally perform best when tag and antenna polarization are properly aligned. Circular polarization can help improve the likelihood of detecting tags at different orientations, although actual performance depends on the tag, antenna placement, and RF environment. For outdoor inventory tracking and access control, circular polarization can be a practical choice when items pass through the reading area in different positions.

A 190° horizontal beamwidth provides broad horizontal coverage, making the APRIA86965CA suitable for RFID installations that need to cover a relatively wide area. Its coverage pattern may help reduce the need to point the antenna toward a narrow target zone, although the final reading area depends on the installation layout, tag position, and surrounding materials.

The APRIA86965CA has an IP65 rating, meaning its enclosure is dust-tight and protected against water jets under specified test conditions. Its aluminum radome provides a rigid enclosure for fixed installations. Before use, check the site’s exposure to moisture, cleaning procedures, chemicals, and temperature to ensure the antenna is suitable for the actual environment.

Yes. A wide-beam RFID antenna can be considered for smart retail and asset tracking when tags need to be detected across a broad area. The APRIA86965CA combines a 190° horizontal beamwidth with circular polarization, which can be useful when tag positions vary within the coverage area. Actual performance depends on tag placement, reader configuration, and the surrounding environment.

The APRIA86965CA uses an SMA-Female connector and has a nominal impedance of 50 Ω. It operates across the 860–960 MHz frequency range. Before connecting it to an RFID reader, confirm the reader’s supported frequency, connector compatibility, and regional operating requirements. A suitable cable or adapter may be needed if the connectors differ.
