Abstract:

The purpose of this study is to present the development of an Ultra-Wide Band (UWB) patch antenna for dual frequency operations. The size of the proposed antenna is 40401.6 mm3 and is excited by micros trip line. The Finite Element Method (FEM) based on high frequency electromagnetic simulation software is used in this investigation. Return loss is obtained below -10 dB from 8.39 to 9.7 GHz. It has achieved stable radiation efficiency 84% with gain 3.81 dB and 4.25 dB in the operating frequency band. The antenna generates two separate resonant frequencies to cover UWB band (3.1-10.6 GHz). Lower resonant mode of the antenna has an impedance bandwidth of 940 MHz (9-8.06 GHz) and the upper resonant mode has a bandwidth of 1 GHz (10.08-9.08 GHz).
