Green wideband RFID tag antenna for supply chain applications

Abstract

In this paper, we demonstrate for the first time an RFID tag antenna manufactured by advanced inkjet printing technology on paper substrate using novel hole-matching technique for reducing the consumption of substrate material and conductive ink while attaining green RFID tags. In-depth electromagnetic analysis is performed methodologically for optimizing the parameters that effectuate the antenna dimensions. The antenna design is optimized for consistent wideband performance and extended read range throughout the complete UHF RFID band (860-960 MHz), while exhibiting benchmarking results when n across cardboard cartons filled with metal or water containing objects.
