Design of circular microstip patch antenna for ultra wide band applications

In this project, an efficient design of circular shaped microstrip patch antenna for Ultra Wide Band (UWB) applications is proposed with partial ground structure. In the recent era, microstrip patch antenna plays a vital role as they are found to be immensely useful due to its compact nature, easy integration and its light weight. UWB systems are popular because of their larger bandwidth and power management efficiencies but the design of UWB based applications requires low profile antennas. It has been found that circular antenna gives better return loss, good directivity and radiation pattern. The line feeding technique used in the proposed model provides good impedance matching, which further improves the characteristics of the antenna.
