Abstract

A T-shape patch antenna loaded with a rectangular slot and fed directly by a 50-Ω microstrip line was optimized using the IE3D simulation tool to improve its bandwidth at a frequency of 2.45 GHz by varying each of four parameters while keeping the other three constant. The impedance bandwidth of the optimized antenna was increased from 40.05 to 81.34 % in the frequency range of 1.682–3.988 GHz. The optimized antenna resonates at 2.181 GHz with high return loss of −47.47 dB. This frequency band is suitable for use in Bluetooth, wireless local area network (WLAN), and Worldwide Interoperability for Microwave Access (WiMAX) applications.
