  Abstract

This study designed a novel circular polarization antenna for a UHF bandwidth RFID reader. As a result of performance test of the antenna designed, it was found that return loss (S11) was about -39.412㏈ at 908.5㎒, which was relatively small, and antenna gain was about 9.09㏈i. And it was confirmed that 50Ω impedance matching was about 49.76Ω and it can be applied for every RFID system. Therefore, the antenna was designed to have higher gain of circular polarization antenna by improving the reception which is one of the most important parameters of the RFID reader, which is expected to be extensively used to recognize multi-tag in the distance.
