ABSTRACT
Multiresonator based spectral signature chipless RFID tag using a novel idea of coupled bunch resonators is presented in this paper. Increasing the surface encoding capacity is an important factor in the development of spectral signature based chipless RFID tag. The amplitude and/or group delay of the spectral signature are utilized for the chipless tag application. The multi-resonator circuit provides a 1: 1 correspondence of data bits. The experimental results for various bit combinations show the potentials of the proposed chipless tag.
