Fully-Printed Wearable Chipless RFID Tags Based on Double-Slit Split-Ring Resonators

In this paper, depolarizing Chipless RFID tags based on double-slit split-ring resonators (DSSRR) with single-layer and dual-layer configurations are investigated. Single-layer tag design could show three resonant dips in the cross-polar spectrum with a thin substrate layer. The designed dual-layer tag demonstrates four resonant peaks, which could achieve robust detection when attached to an absorptive or reflective platforms in a dynamic environment. An on-body experiment for the dual-layer tag is performed to validate its wearability. Both designed tags are fabricated through fully printed process, which is low-cost and suitable for the mass manufacturing.
