Analysis of chipless RFID tags based on circular-SRR and Koch snowflake fractal for space-reduction and bit-coding improvement
2021 IEEE Indian Conference on Antennas and Propagation (InCAP), 2021•ieeexplore.ieee.org
Chipless Radio Frequency Identification (RFID) has established itself as one of the
prominent techniques for identifying and detecting objects. Unlike optical barcodes, tagging
technology does not need line-of-sight communication. The design and analysis of chipless
RFID transponders using the circular Split-Ring Resonator (SRR) and the Koch snowflake
fractal of the third iteration are discussed in this work. The Radar Cross Section (RCS) and
frequency coding approaches are studied, as well as a comparison, demonstrating key …

Chipless Radio Frequency Identification (RFID) has established itself as one of the prominent techniques for identifying and detecting objects. Unlike optical barcodes, tagging technology does not need line-of-sight communication. The design and analysis of chipless RFID transponders using the circular Split-Ring Resonator (SRR) and the Koch snowflake fractal of the third iteration are discussed in this work. The Radar Cross Section (RCS) and frequency coding approaches are studied, as well as a comparison, demonstrating key characteristics of the transponders such as physical footprint and spatial densities are investigated. As a result, tag production costs are reduced. The maximum RCS are found to be -22.24 dBsm and -25.6 dBsm for transponder 1 and 2 respectively.
