Abstract

An Antenna is a metallic structure that transmits and receives radio waves. Antennas come in all shapes and sizes from tiny microstrip antenna for biomedical applications to very big parabolic reflector antennas for satellite communications. A Super Wideband Square Monopole Antenna is designed on Arlon AD260A and FR4 Epoxy with CPW-feed structure. Notched bands are obtained by embedding inverted E-shaped stub, using C-shaped parasitic element above radiating patch and etching rotated U- shaped slot in the ground plane. Proposed Antenna has the capability of operating in Ultra Wide band frequency range of (2.534-3.244)GHz with a minimum S11 value of -14.9846dB, (4.414-6.300)GHz with S11 value of -31.9643dB, (6.728-7.150)GHz with S11 value of - 12.3336dB and (13.481-15.870)GHz with S11 value of - 21.9915dB. The maximum gain obtained is 5.86dB in 3-D Omni directional pattern. The minimum VSWR obtained is 1.05. Key Words: Super Wideband, Ultra Wideband, CPW, X- Band, Ku-Band. 1.INTRODUCTION
