Abstract : A novel encoding technique using group delay characteristics for chipless Radio Frequency Identification (RFID) tag is demonstrated in this paper. It uses phase-frequency signature along with a temporal analysis. This chipless tag comprises of cascaded transmission line sections coupled at alternative ends (which are also known as C-sections) along with a planar ultra wideband monopole antenna. The structural mode of the antenna is used as the reference signal. Commensurate C-section is used to generate the identification. A 2 bit coding is demonstrated as an example in this paper. The approach is validated with simulation results.
