Design of specific ultra wide band antenna for satellite communication

Abstract

Ultra Wide Band usually denotes to signals or systems having a large rel- ative or a large absolute bandwidth. This large bandwidth provides a precise improvement in signal robustness and information content. This also deluges the high data rate transmission. The previous decade endures a confluence of technological, economic and political covenant that empow- ered the usage of Ultra Wide Band systems. The development and utility of Ultra Wide Band technology demands more acceleration in antenna design. The design aspect of achieving the Ultra Wide Band is more challenging due to the requirement of a high fractional bandwidth of more than 25% in the Ultra Wide Band range that covers 3.1 GHz to 10.6 GHz. It also requires the antenna to have a uniform satisfactory characteristic over the entire operational frequency
