UHF RFID Tag Using Polycarbonate Material

Abstract

This paper proposes an improved UHF RFID tag using low cost materials such as transparency paper (polycarbonate) as the substrate and aluminum tape as the radiating element. The main contribution of this method is the reduced size of the UHF RFID tag compared to the readily available tags. The tag is developed by outlining a bowtie antenna with meandered lines. To test the effectiveness of the proposed method, CST simulations are carried out under various parameter changes such as the size, the shape of the bowtie, and the width of the meander line. The result shows up to 30% decrease in size compared to the readily available UHF RFID tags.
