ADDED, M., et al. High-Performance Chipless Radio-Frequency Identification Tags: Using a Slow-Wave Approach for Miniaturized Structure. IEEE Antennas and Propagation Magazine. 2019, 61(4), 46-54. ISSN 1045-9243. DOI 10.1109/MAP.2019.2920664.
A novel planar chipless radio frequency identification (RFID) tag is introduced in this paper. The tag is composed of miniaturized multiple reflecting antennas based on a slow wave structure. To validate the proposed approach, a tag with a coding capacity of 16 bits has been designed with a compact size of 15 × 21 mm². Tags with different pattern configurations have been performed using a Rogers RO4003 substrate and its radar cross-section responses have been measured. Compared to conventional multi-resonator tags, the proposed tag offers a good miniaturization ratio and spectral coding efficiency. In addition, the measurements revealed high Q factor and coding robustness which demonstrates the efficiency of the used approach to develop high performance chipless tags.
