5dBi PCB UHF RFID Antenna – 70x70mm

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.

Yes. A compact UHF RFID antenna can be integrated into electronic devices when sufficient space is available and the surrounding materials do not excessively affect RF performance. The APRIA869605CD measures 70 × 70 × 10 mm and weighs 0.023 kg, making it suitable for consideration in embedded RFID equipment and customized reader systems.

Circular polarization can help maintain tag readability when tag orientations vary within the reading area. The APRIA869605CD uses circular polarization in a compact PCB format, making it an option for embedded RFID systems where tagged items may not always be positioned in the same way. Performance depends on the tag, enclosure, and antenna placement.

The APRIA869605CD uses an SMA-Male connector and has a nominal impedance of 50 Ω. Before connecting it to an RFID reader, check that the reader or coaxial cable has a compatible connector interface and supports the antenna’s 860–960 MHz operating range. A suitable adapter may be required if the connector types differ.

The APRIA869605CD has a horizontal beamwidth of 120° and a vertical beamwidth of 114°, providing broad coverage in both principal planes. This can be useful when integrating an antenna into equipment that needs to detect tags across a relatively wide area. Actual coverage depends on mounting position, tag placement, and nearby materials.
