A circular UWB antenna with partially abandoned ground structure is designed for UWB applications which is called Ultra Wide Band antenna. At first, circular ring antenna is designed by presenting a Defected ground structure. Later, disc and rectangular slots are embedded in a circular patch to upgrade the transfer capacity. The proposed plan extended over the bandwidth of 2.4-13.6GHz underneath - 10dB. Proposed 1.5mm reception apparatus has structure and having thickness of 1.5mmand dielectric consistent of 4.4mm was made on FR-4 substrate. The presentation of the planned design analyzed in terms of return loss, Voltage standing wave ratio, radiation design, gain attributes and surface current circulations. Further, design antenna is analyzed and compare with existing antenna with minimal in size.
