An RFID UHF antenna is a device used in Ultra High Frequency (UHF) RFID systems to transmit and receive radio frequency signals between RFID tags and RFID readers. These antennas operate typically within the 860 MHz to 960 MHz frequency range and are widely used for long-range RFID applications.

RFID UHF antennas help improve communication between RFID readers and tags, enabling fast and accurate data capture without direct line-of-sight scanning.
