Fabrication and performance evaluation of ultralow-cost inkjet-printed chipless RFID tags
2012 (English)Conference paper (Refereed)
This paper studies the performance of inkjet-printed chipless RFID tags based on planar inductor-capacitor resonant circuits. Besides using double-sided printing, a sandwiching process is introduced to fabricate the tags in order to eliminate the need of through-substrate via and match roll-to-roll processing. Due to lower conductivity (~1.25E+7 S/m) and smaller thickness (~1.7μm) of printed conductors with silver nanoparticle ink, the resonant peaks of inkjet-printed tags exhibit around as twice of half-power bandwidth and 60% of maximum reading distance as the etched tags from bulk copper. Nevertheless, the inkjet-printed tag performance is sufficient for many applications, and it can be adjusted and improved by printing and sintering processes.
