Brajesh Kumar Gupta, Sumita Mishra

Abstract: Satellite communication and Wireless communication has been developed rapidly in the past decades and it has already a dramatic impact on human life. In the present time in commercial and government communication system has been develop low cost, minimal weight, minimal size, low profile antenna, the capable of maintaining the performance over a large spectrum of frequencies. This paper emphasizes the use of Defected Ground Structure (DGS) technique in microstrip patch antenna. This circular disc or patch antenna is designs are simulated using the IE3D software. And try to find out the different-different condition the maximum gain output and bandwidth. The simulated and measured results are in close agreement which validates the role of the designed antenna for operation in wireless applications from 5-15GHz. A comparison is drawn between the performances of the antennas in terms of gain, return loss, VSWR of the antennas

Keywords: Broad band, coplanar waveguide, Defected ground structure, Circular patch antenna.
