Design of an UWB Patch Antenna for Dual Frequency Operations
並列摘要
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 40×40×1.6mm^3 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 -10dB from 8.39 to 9.7GHz. It has achieved stable radiation efficiency 84% with gain 3.81dB and 4.25dB 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 (9-8.06GHz) and the upper resonant mode has a bandwidth of 1GHz (10.08-9.08GHz).
