In this research work, from the designing of a circular slotted rectangular shaped antenna for full filling the requirements of S-Band and C-Band applications at 3.29- 7.98 GHz frequency. It is observed that the value of wideband in proposed antenna is 4.687 GHz (4687 MHz) which is very wide with respect to wideband of reference antenna which has 4.28 GHz (4280 MHz) bandwidth. So the difference between proposed antenna and reference antenna is 4.687 – 4.280 = 0.407 GHz= 407 MHz. So the value of wideband is very large than the reference antenna. The parametric study of the designed antenna has been attempted in this thesis. The physical parameters examined in this study include the dimensions and locations of the substrates and their dielectric constants, feed line, ground plane coupling slot and patch.
