Abstract

In this paper, a CP MIMO antenna system design capable of UHF band operation is presented. By using circular polarization and antenna diversity by selection of the antenna supported by RFID reader chip sets, This MIMO antenna system can have high receiving signal strength and larger antenna beam coverage area, making this design a suitable candidate for RFID application in warehouse tracking. Parameters of the antennas such as impedance bandwidth, axial ratio, radiation patterns and gains are presented and discussed herein.
