| Summary: | This paper introduces a novel compact planar multiresonator with high surface encoding capacity, specifically designed for chipless RFID tag applications. The tag features eight Stepped Impedance Resonators (SIR) that operate within the 2.85 GHz to 5.37 GHz frequency range, providing a bandwidth of 2.52 GHz. A key characteristic of the tag is its ability to achieve unique resonating frequencies by modifying the dimensions of the stem and the width of the serif of each Stepped Impedance Resonator. The prototype tag is designed and fabricated on an RT5880 lossy substrate, which has a dielectric constant of 2.2 and a loss tangent of 0.0009. The tag’s identity is encoded in the spectral domain using the Absence or Presence Coding (APC) Technique and the Frequency Shift Coding (FSC) Technique. The reliability of the proposed design is validated through measured results from the fabricated prototype. |
