In this research paper author proposed a new DGS design to modify the antenna from single band to double band
antenna. Initially the antenna was designed at 1.38GHz later in this paper, author proposed a new design of DGS to modify
this antenna into double band. To achieve this very important band characteristic author proposed three parallel strips
shaped symmetrical DGS in the ground plane. This symmetrical DGS on the other side of the patch increases the fringing
field which consequently increased the parasitic capacitance. This coupling of patch and ground made the antenna a double
band antenna
