A novel design of chipless RFID tags based on alphabets

This paper presents an approach for the design of chipless RFID tags by using standard alphabets. To illustrate this approach, the paper considers the alphabet letters (a, b and c) that are realized using copper etching on 0.5mm thick Taconic TLX-8, with a relative permittivity of 2.55 and loss tangent of 0.0019. As expected, simulation results demonstrate that the exploitation of resonant frequencies visible in the backscatter signal can be used for purpose of identification. These simulation results are validated by the experimental measurement.
