A study on a coding method for chipless RFID tags using multimode stepped impedance resonators

摘要

References(14) Stepped impedance resonators (SIRs) are composed of multiple transmission lines having different characteristic impedances, and can control higher-order mode resonance frequencies. Here, by using these properties, identification codes from a resonator were systematically generated by introducing symmetric multimode SIRs composed of same-length transmission lines. In the other direction, resonator codes were identified by detecting their higher-order mode resonance frequencies. This paper describes these resonance properties and experimental results from multimode SIRs, and discusses their applicability in chipless RFID tags.
