This letter studies the possibilities of manufacturing copper-based passive ultrahigh frequency (UHF) radio frequency identification (RFID) tags using inkjet and thermal printing on two substrate materials, polyimide (Kapton), and a polyester-based substrate (Flexcon THERMLfilm). Both printing methods are tested to fabricate different tag designs, and the performance of successfully printed tags is...
We characterize two nanoparticle inks for the fabrication of low-cost passive UHF RFID tags on a novel polyester-based substrate (Flexcon THERMLfilm). We developed optimized printing parameters for Silver (Harima NPS-JL) and Copper (ANI Cu-IJ70) inks, fabricated the tag antennas and sintered them using thermal and photonic sintering. The tag performance is evaluated through wireless tag measurements,...
This paper investigates the effects of conductor thickness on the performance of passive RFID tags fabricated using inkjet technology. Judging from the obtained results the performance of printed tags continues to increase as more conductive layers are added. However, the results show that the amount of performance improvement reduces with increase of the number of layers.
