This paper presents performance optimized RFID tag antenna, developed by using commercially accessible paper substrates and advanced inkjet printing process to guarantee mechanical flexibility and ultra-low production costs. The proposed antenna structure can endure the variations which emerge in electromagnetic properties of paper substrate due to varying environmental effects. Hole-matching technique is implemented to eliminate the matching network for reducing the consumption of conductive ink. The proposed structure is uniquely evaluated by demonstrating, sustainability and environmental impact analysis that validate the potential for ultra-low cost mass production of RFID tags for future generation of organic electronics. The antenna performance is assessed for cardboard cartons exclusively containing metal cans and water bottles. The experimental characterization of the proposed antenna endorses the wider bandwidth to cover UHF RFID ISM band (860-960MHz), which empowers its usage throughout the globe for supply chain applications. The improved design effectuates return loss of better than -15dB over a wide frequency range while exhibiting outstanding readability from 10.1 meters.
