In this research work, design of Ultra-Wide-band microstrip line feed partial ground structure corner rounded rectangular microstrip patch antenna is presented. Design is implemented on FR4 substrate, and results implies that, just by making lower corners of rectangular patch and upper corners of partial ground rounded form sharp edges, good impedance bandwidth is achieved for the proposed antenna. Presented design full fill the essential bandwidth, needed for Ultra-Wideband applications defines by FCC from 3.1GHz to 10.6GHz. Proposed design resonates from (3.21GHz to 12.72GHz) with impedance bandwidth is of 9.51GHz has a moderate gain of 2.88dBi. Parametric analysis is presented to show effect of corner round and ground gap on performance of antenna.
