PROJECT TITLE :

Real-World Implementation Challenges of a Novel Dual-Polarized Compact Printable Chipless RFID Tag

ABSTRACT:

A completely unique compact printable dual-polarized (DP) chipless radio-frequency identification (RFID) tag is presented together with its real-world implementation challenges. Initial, the DP tag with simulation and measurement results is presented, where 'U’ formed slot resonators are re-employed in each vertical (V) and horizontal (H) polarizations to double the encoding capacity within a mounted bandwidth. Next, slot-length variation encoding technique is added to scale back the tag size by fifty%. When that, a sixteen-bit proof of concept DP tag is developed that achieved sixteen.half-dozen $rm bits/cm^2$ data density, that is the best among the reported works. Next, a step-by-step guideline is presented to overcome the real-world challenges for implementing printable chipless RFID tags, which starts with a detail study on the impact of ink conductivity, and permittivity and loss tangent of the substrate on the tag performance. Then, a fast approximate substrate characterization technique is presented, that is verified by measurement of thermal printed patch tags. Finally, tag printing procedure on paper employing a thermal printer is briefed, that is followed by a discussion on some printing inaccuracies and their plausible solutions. Of these analysis will build a firm understanding and sensible insight on implementing the proposed promising conductive ink printed chipless RFID tag for identification, authentication and sensing.
