Abstract

Modern communication system require antenna with wider bandwidth, smaller dimension, high gain and high efficiency. Various antennas for wide band operation have been studied for communication and radar system. The proposed antenna has been simulated and optimized using IE3D Simulator to cover standard frequency bands like at (3.54GHz,4.071GHz,9.061GHz), ISM/WLAN/Bluetooth band (Operating freuencuies:2.32GHz), Wi-Max(3.4-3.69GHz,Operating Frequencies: 3.54GHz), Hiper Lan2(2.12-2.32GHz, operating frequencies: 2.32GHz) communication. In this Dissertation, We compare both result and we analyze that like VSWR (VSWR≤2) and Return Loss dB (Return loss ≤-9.5 dB) and almost 100% radiation Efficiency for 2.53GHz frequencies. I also fabricate this antenna and measure return loss for various resonant frequencies. Practical result shows antenna resonant at ten different frequencies within range 1-20GHz. which shows antenna work as good multiband antenna.
