A compact monopole microstrip notched ultrawideband (UWB) with rotated D-shape slots in the patch is presented. By introducing a new inverted D-shaped notch in the radiating plane, band-notch which is about 5.14 to 6 GHz and 6.21 to 8.66 GHz and 6.21 to 8.66 GHz are achieved. The proposed antenna offers 127% bandwidth overall dimension of 13×17×1.6 mm3. The experiment results demonstrate that the proposed antenna can well meet the requirement for the UWB communication in spite of its compactness and small size. VSWR is nearly under 2 which are very good for wireless application. The characteristics of compact size, low profile, and simple structure make the proposed antenna suitable to use for the UWB wireless communication applications
