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 applicationsواژگان کلیدی
