This study introduces printable, chipless radio frequency identification (RFID) tags shaped as letters. These unique alphabet designs enable robust, visually recognizable identification using radar cross-section signatures, enhancing coding density and security.

Area of Science:

  • Electromagnetics and Microwave Engineering
  • Materials Science for RF Applications
  • Wireless Communication Systems

Background:

  • Traditional radio frequency identification (RFID) tags often feature complex geometries, limiting their compactness and printability.
  • Visual recognition of transmitted data in real-time via radio frequency (RF) waves is a desirable feature for identification systems.

Purpose of the Study:

  • To present a novel technique for designing compact and printable chipless RFID tags using alphabet shapes.
  • To analyze the unique frequency response signatures of alphabet-shaped tags for robust identification.
  • To investigate the impact of font variations on tag performance.

Main Methods:

  • Fabrication of alphabet-shaped chipless RFID tags using copper etching on a dielectric substrate (TLX-8) with a ground plane.

  • Simulation and measurement of monostatic radar cross-section (RCS) using a dual-polarized Vivaldi antenna (6-13 GHz).
  • Analysis of co- and cross-polar RCS characteristics for different font types, sizes, spacing, and orientations.

    • Main Results:

    • Alphabet-shaped tags exhibit unique dips in their backscattered RCS frequency response, distinguishing individual letters.
    • Demonstrated printability and visual recognition capabilities with a coding density of 2.63 bit/cm².
    • Achieved good agreement between simulated and measured RCS results for both co- and cross-polarized signals.

    Conclusions:

    • The proposed alphabet-shaped chipless RFID tags offer a novel, compact, and printable identification solution.
    • Utilizing both co- and cross-polar RCS characteristics enhances coding density, security, and detection robustness.
    • The method allows for reliable detection of alphabet tags with varying fonts and improved signal-to-noise ratio (SNR).
