In this article, design, analysis and comparative study of three different feeding techniques for UWB antennas, namely the microstrip feed, CPW feed and ACS feed is carried out. First design microstrip feed line UWB antenna, which consists of circular radiating patch & destructive ground structure (DGS) of length Lg and width Wg. The ACS feed structure provides almost 50% size reduction as compared with the traditional microstrip or CPW feed antenna. The proposed antennas are fabricated on a FR-4 substrate of thickness h = 1.6mm having loss tangent of 0.02 and dielectric constant of ξr = 4.4 and has been analyzed using HFSS EM simulation software. The final ACS feed UWB antenna provides an impedance bandwidth of VSWR ≥2 over the frequency band of 2.4–11 GHz. The proposed antennas exhibits good electrical characteristics in both time and frequency domain giving stable gain, almost omni-directional radiation patterns making the antenna suitable for wireless applications.
