The research article presents a comparative analysis of stacked and unstacked fractal antenna geometries. Four fractal antenna geometries, namely, an aperture coupled bow-tie antenna, a scaled aperture coupled bow tie with the same dimension on upper and lower patch, a stacked bow-tie geometry with smaller upper patch and larger lower patch, and a stacked geometry with larger upper patch and smaller lower patch with bow-tie antennas for both stacked layers are studied and analysed. The overall size of antenna is 57.84 × 57.84 mm2 for all the four geometries. The ground used for an unstacked geometry is DGS, i.e. defected ground slot, and ground used for stacked geometry is partial ground. The effect of both the grounds has been shown and studied. The submitted antenna results for all the four geometries are analysed and studied in terms of impedance bandwidth, broadband gain and VSWR.
