 Abstract-We report the design and first results of a Re-Configurable RF-encoding particle (REP) for Chipless RFID tag, based on a Nafion-CBRAM Cell. The developed tag consists of a modified shorted dipole as REP, equipped with a Copper-Nafion ®-Aluminum Metal-Insulator-Metal (MIM) non-volatile Ionic-Bridging switch. The MIM switch is similar to an RC parallel network, which tunes the electrical length of the resonator. The Chipless tags switch between two different resonance frequencies, in the Set and Reset state of the switch. An electrical model is also developed for the REP, to explain the mechanism of switching. The experimental results are in close agreement with the simulated results using commercial EM Simulators. This study is a proof of concept of electronically reconfigurable Chipless tags based on integrated switches which have the potential to be directly printed along with the tag.
