Miniaturized Printed Yagi Antenna for 2.45GHz RFID Readers

In this paper, a miniaturized printed Yagi antenna with bent arms is proposed for radio frequency identiflcation (RFID) readers operating at the frequency of 2.45GHz. The pro- posed antenna design, analysis and characterization has been performed using CST electromag- netic simulation software. The antenna was fabricated with ROGERS4003 substrate. Re∞ection coe-cient and directivity results were simulated and measured.
