摘要

A highly compact chipless tag based on Frequency coding technique using Spiral Resonators is proposed in this paper.Spirals are well known metamaterial structures and thus capable of sharp resonance,and hence Spiral Resonators can serve as a good candidate for RF Identity Tags.The bit capacity of the proposed tag is 10 bits per sqcm.The prototype of the tag is fabricated on a low-cost substrate of dielectric constant 4.4 and loss tangent 0.02.The overall dimension of tag is 15.4 x 3 x 1.6mm3.Two methods for reading the tags are also discussed in this paper.Scope for bit enhancement is also provided.
