Placement of mushroom electromagnetic bandgap (EBG) structures at the inset feedline of patch antenna operating at 4.8 GHz is analysed, in this study. Proposed design for (i) single patch and (ii) two-element patch array exhibits significant improvement in return loss, bandwidth and mutual coupling...
