Ultra-Wide Band Microstrip Patch Antenna for C and X -Band Applications with Effect of Copper Thickness

Abstract

An ultrawide band partial ground miniaturized rectangular shape microstrip patch antenna is investigated in this paper. The size of the proposed antenna is 17×10×1.6 mm3 and is excited by microstrip line feed which operates for C band and X- band. In this article we have compared the variation in the output by changing the thickness of copper of the proposed antenna from 35μm and 70μm. The design is simulated by Ansoft’s HFSS13v which is based on finite element method then is fabricated using wet etching method and finally measured by copper mountain reflectometer R140 version. The performance of the rectangular shaped antenna is analyzed on various parameters like reflection coefficient, VSWR, group delay, gain, radiation pattern and radiation efficiency. The measured and simulated results reveal that proposed antenna resonates from 6.3-12GHz giving ultrawide band with bandwidth impedance of 62.9% with the gain of 3.94dBi and maximum radiation efficiency of 95% targeted for satellite communication, radars and radio navigation applications.
