摘要：In this paper, a simple structure microstrip patch antenna with high front-to-back ratio is proposed forUHF-RFID tag at 870MHz on sapphire material as substrate. The performance of general structure rectangular patchantenna is designed and analyzed in ANSOFT-HFSSV13.0 simulator and the antenna characteristics are interms ofreturnloss, radiation pattern, half power beamwidth, front to back ratio and gain. Later, the work is extended todifferent patch shapes and compared the performance of all antennas. Hexagonal patch antenna is practically designed,analyzed with network analyzer and compared to simulated results.
