Abstract
A compact, robust, chipless radio frequency identification (RFID) tag is proposed. Resonant elements patterned in a concentric fashion encode data in the spectral domain employing frequency shift encoding. The proposed tag encodes 28.25 data bits over a miniscule physical footprint of 25 x 25 mm(2). The formulated scheme is demonstrated to be viable for encoding of temporal variables. The electromagnetic performance of the presented design is investigated for different laminates: Rogers RT/duroid (R) 5880 and Taconic TLX-0. Multiple tag prototypes employing a variety of substrates are realized and evaluated for in-laboratory performance. The proposed design is compared with existing work reported in literature. Code density of 4.52 bits/cm(2) has been successfully achieved. The tag design operates from 3.07 to 10.6 GHz and is readily realizable on flexible laminates. Smart retail, intelligent packaging, adaptive ticketing, and similar time-related applications can be materialized using the proposed tag.
