Performance assessment of printed RFID reader antenna

In this paper, we characterize a printed loop antenna at high frequency (HF). The low-cost printed antenna will be used in a HF RFID smart shelf system for a low cost solution. The performance of the printed antenna is compared with an antenna made of PCB (copper) at 13.56 MHz in terms of impedance matching, field response, Q-factor, and detection range. The investigation is carried out by experiments.
