UHF RFID Tag Based on Modified Dihedral Corner for Enhanced Read Range and Broadband Operation

Abstract

This paper presents the design and development of a novel UHF RFID tag which exhibits enhanced read range over the entire UHF RFID band of 860-930MHz. This novel UHF RFID tag consists of an antenna based on modified dihedral corner with an embedded double T-match and a Murata LXMS 31ACNA010 chip attached to the terminals of the antenna. Measured read range variations over the azimuth and elevation angular ranges show enhanced read range over wide angular ranges as compared to conventional RFID tags.
