Analysis of circular patch antenna of 2-3ghz for electromagnetic applications

This paper present analysis of bandwidth of circular patch antenna for electromagnetic (EM) applications at frequency 2-3GHz for reflection coefficient less than -10 dB. The final dimension of the proposed antenna is 48mmx30mm (LsxWs) for its FR4 substrate with thickness of 1.6mm, circular patch of radius 12.5mm and a feedline with 25mmx3mm (LpxWp). Thickness of circular patch and feedline both at 0.035mm.The proposed antenna is wideband of 24.50%, highest gain of 3.292 dB and in Omni-directional radiation pattern. Circular patch antenna is chosen because of its better directivity, easiness in fabricating process and in analyzing its structure to provide a best wideband. In EMR, it preserves Omni-directional radiation characteristic because of it equally well in process of receiving signal. Ultimately, the operating frequency range is determined and the design is analyze to be used for EM application. The performance of the designed antenna was analyzed in terms of return loss provided its stable Omni-directional radiation pattern and gain
