Fig. 1. View of chipless tags a) Tag 3 b) Tag 4 c) Tag 5. Dimensions are given in Table I - "RFID chipless tag based on multiple phase shifters" In this study, prototypes of two distinct 8-bit chipless RFID tags operating in 3–6 GHz utilising L-resonators discussed in Section 2 are reported. The chipless tags have been designed using CST Microwave Design Studio and printed on the Roger RT 5880 substrate.

To model a chipless RFID tag with multiple resonators, several RLC circuits as resonators can be added. In this model, we have separated the sources to vary the proportion of energy that is reflected by the resonant modes and the structural mode.When multiple chipless tags are in the interrogation zone of a reader, anticollision algorithms needs to be employed for correct tag identification. Compared to conventional tags containing silicon chip, chipless RFID tag uses an entirely different technique to en-code data.

It is based on changing the phase of multiple resonators that behave as phase shifter. This technique brings a much higher reliability than for the actual absence/presence of resonance encoding way. The design proposed is based on 5 reflective strip resonators having resonant frequency starting from 2.5 GHz to 6.5 GHz.A compact passive two-bit metamaterial based phase-modulated chipless RFID tag at 2.4GHz is presented. The chipless RFID tag consists of a monopole antenna and CRLH delay lines operating in the left-handed (LH) region with distributed digital phase modulating sections. This paper presents a compact 12-bit chipless RFID tag loaded with 12 bending arm elements with an absence or presence coding technique, where the latter three arms are used to encode FSC to increase the coding capacity of tags. The RFID chipless tag presented in this article uses a new technique for data encoding. It is based on changing the phase of multiple resonators that behave as phase shifter.
