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...
In this paper, we present environmentally friendly UHF RFID tag antennas that are manufactured by inkjet printing silver nanoparticle ink on a plain paper substrate after finding the most efficient manufacturing parameters and the optimal number of printed layers. The RFID ICs in this work are attached with environmental-friendly and cost-effective conductive adhesive, and the ready RFID tags are...
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,...
In this paper, the parameters for inkjet-printing and photonic sintering of silver and copper nanoparticle inks on flexible polyimide substrate were studied by manufacturing simple line patterns. The results were then utilized to manufacture passive ultra high frequency (UHF) radio frequency identification (RFID) tag antennas on polyimide substrate. The tag's performance was evaluated by wireless...
This paper presents an overview of various radio frequency identification (RFID) tag fabrication methods and briefly describes the advantages and disadvantages of each method. The purpose of this paper is to provide readers with the RFID fabrication techniques that can be applied in laboratory scale experiments. The performance results of laboratory made RFID tags based on two fabrication methods...
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.
