Abstract

A thin passive tag antenna for Radio Frequency Identification (RFID) application for smart billing system over the counter using the Ultra High Frequency (UHF) range of 860-867 MHz is being presented in this paper. The structure of the tag antenna is a simple dipole antenna but with a tip loaded effect by widening the antenna ends on both sides to reduce the size of the tag. The antenna structure is further matched to the RFID chip impedance by the addition of a T-match shaped stub at the center of the antenna. Simulation is carried out using Ansoft HFSS software. The simulated result shows a good impedance matched antenna structure with reasonable return loss indicating the matching of complex conjugate impedance with the chip, strong radiation efficiency (88.1%), gain, and long range read range decent for billing system purpose.
