Polarimetric Radar Barcode: A Novel Chipless RFID Concept With High Data Capacity and Ultimate Tag Robustness

The architectures of two innovative compact orientation independent chipless radio frequency identification device (RFID) tags for emerging applications such as the internet of things are presented. These tags, when illuminated, generate resonant frequencies in the radar cross-section backscattered spectrum, which are used to encode the data. These are based around L-type resonators, which can be read from front and back using linear polarisation waves as they do not have the ground plane. The first tag design consists of L-resonators in the lower triangular of the substrate, and thereby mutual coupling is increased as a reduction in the size. The second tag design incorporates alternate L-resonators in both halves of the substrate and exhibits reduced mutual coupling and enhanced printing strength but with a reduction in bit density. The proposed concept is demonstrated through prototypes of 8-bit chipless tags on Rogers substrate. These tags require very low bandwidth to encode 8-bit and occupy a small board size of 20 mm × 20 mm, and these are considerable improvements in the development of chipless RFID.

“…A chipless RFID system needs to be compliant with UWB regulations in the band 3.1 -10.6 GHz [15,16]. Higher frequency bands are also being used in chipless RFID for different applications [17,18], however these frequency bands are not the subject of interest in this article. The next section introduces chipless RFID tag technology.…”

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 × 25 mm2. 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® 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/cm2 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.
