摘要

This paper illustrates the effect of defected ground structure (DGS) on a biconvex patch antenna. Comparative results have been obtained when DGS is applied to the base just under the patch and a line feed technique is provided. The comparison includes the optimization of DGS with different radius and length values. DGS with different shapes like circular and rectangular is used to obtain the comparative results. The comparative results explain that the proposed reshaped circular patch antenna has a better antenna gain and an even wider bandwidth as of the previous structure without the implementation of DGS. Substrate has a dielectric material (FR4-epoxy) with a relative permittivity of 4.4. The simulated parameters like S_(11) parameter, antenna gain, VSWR, directivity, radiation efficiency, peak directivity are obtained by using HFSS software for the entire band ranging from 50 to 60 GHz applications.
