Abstract :
In chipless RFID tags, the structure functions both as a scatterer and an encoder in response to the incident wave. The embedded resonances on the tag incorporate the ID of the tag and its RCS determine the read-range of the tag. In this paper, the theory of characteristic modes is employed to study the resonant and radiation modes of chipless RFID tags. By studying the effects of various parameters on the characteristic modes, some hints are proposed to improve the characteristics of chipless RFID tags for high density applications.
