Abstract:
1. A small size Ultra-Wideband (UWB) antenna, comprising: a radiation element including one radiation conductor, one matching element and one antenna feeding element, and said matching element having length between 1 to 5 mm and width between 0.5 to 1.5 mm for changing current distribution of said radiation conductor to provide impedance matching for a high frequency band including operating frequency at 7.97 GHz; a dielectric substrate, upper and lower surfaces of said dielectric substrate having one signal feeding element and one conductor plane thereon, respectively, and said signal feeding element connecting electrically to said antenna feeding element; and a dielectric element carrying said radiation element; wherein said antenna feeding element is connected to an edge of said radiation conductor and said matching element extends from said edge into said radiation conductor immediately adjacent to said antenna feeding element.
