Bendable ultra-high frequency radio-frequency identification tag antenna for retail garments using nonuniform meandered lines

Abstract

A bendable ultra-high frequency (UHF) radio-frequency identification (RFID) tag antenna using nonuniform meandered lines for retail garments in the textile industry is presented. Based on an earlier UHF RFID tag antenna using nonuniform meandered lines, the proposed tag is fully bendable and aimed to be embedded in retail garments for long-life cycles. As a result, a relatively low cost, wideband, compactness, and good conjugate matching with good dipole-like read range is presented. Results showed an antenna with a wide bandwidth of 900 MHz and a long read range of 10.1 m making the UHF RFID tag antenna using nonuniform meandered lines a potential candidate for retail garments in bendable applications of the textile industry. Simulations are corroborated by measurements and are in fairly agreement.
