A novel H-shaped cavity based RFID chipless tag

This paper describes the design, manufacturing and testing of a new RFID chipless tag linearly polarized, with improved data capacity, reduced size. The tag generates data in the frequency band of 3.5-6.5 GHz. It consists of an H-shaped cavity and a circular UWB antenna associated by means of transmission line. An original shape and an original association are realized, and a novel chipless tag is proposed and experimentally verified. In this work, we present the experimental characterization of the H-shaped cavity and the circular antenna separately, and the system simulation of the two components associated, proving the feasibility of our novel configuration.
