Abstract

A planar wideband patch antenna for ultra�high frequency (UHF) radio frequency identification (RFI D) tag for metallic applications is presented in this research work. Three different shape patches are inductively coupled to a triangle loop to excite three resonances close to each other to f orm wide impedance bandwidth for universal application UHF ( 860�960 MHz) RFID. The structure of the proposed antenna ex hibits planar profile to provide ease of fabrication for c ost reduction well suited for mass production. The simulation of the antenna was carried out using Finite Element Method (FEM) b ased software, Ansoft HFSS v13. The performance of the d esign was verified by the simulation and measurement results which show good agreement. The simulated and measured impedanc e bandwidth of 113 MHz and 117 MHz (return loss ≥ 6 d B) was achieved to cover the entire UHF RFID operating fre quency band worldwide.
