Design of Antenna for UHF Near-Field RFID Reader

Abstract:

A segmented loop antenna is presented for ultra-high frequency (UHF) near-field radio frequency identification (RFID) reader. The segmented antennas have been constructed that can operate at resonant diameters while still providing good magnetic coupling. The antenna printed on a FR4 printed circuit board (PCB) with an overall size of 170× 170 × 1 mm3 achieves good impedance matching and uniform magnetic field distribution over an operating bandwidth of 840–1120 MHz, which is desirable for UHF near-field RFID reader applications.
