Ribbon-Shaped Antenna Design for UHF RFID Tag using Transparency Paper Material

This paper presents an improvised dipole antenna that is designed for passive Radio Frequency Identification (RFID) tag utilizing transparency paper (polycarbonate) for the substrate and copper tape as the radiating element. The main positive impacts of this method are the performances (realized gain G, return loss RL and total efficiency ηt) of the antenna design for Ultra High Frequency (UHF) as well as the compactness compared to the straight antenna design for RFID tag. The efficacy of the proposed method is attained by generating the simulation through Computer Simulation Technology (CST) and modifying the various parameter changes namely to the size, the shape of the ribbon antenna, the gap of discreet port and the width of the meander line. In comparison with the straight antenna design, the rounded ribbon antenna shows an improvement in terms of realized gain, return loss, total efficiency and size of the design which are 2.052 dBi, -33.98, 99.57% and 125mm respectively.
