A printed rectangular monopole antenna fed by a tapered coplanar waveguide (CWP) with a band-notched characteristic is proposed for ultra wideband (UWB) applications. It is shown that the notched or rejected band with a wide operating bandwidth is obtained by embedding an E shape slot in the rectangular radiation patch and its parameters studied in detail. The notched band is controllable by adjusting the lengths and location. With a compact size of 36times34 mm2, the proposed antenna showing UWB omni-directional radiation patterns that is suitable for UWB applications.
