Abstract :
A metal-plate backed metamaterial-inspired loop antenna is proposed for both near-field and far-field radio frequency identification (RFID) applications at ultra high frequency (UHF). The antenna is composed of a distributed capacitor loaded segmented loop and a backed metallic plate. The antenna prototype printed onto an FR4 printed circuit board (PCB) with an overall size of 250 mm × 250 mm × 25 mm shows desirable performance for both near-field and far-field applications over the frequency range of 900-960 MHz. Hence, it is very promising for UHF RFID reader applications.
