A coplanar waveguide fed (CPW-fed) ultra wideband (UWB) antenna with dual band- notched characteristics is proposed. In this antenna, an E-shaped patch and a ground plane truncated with two mirror notches are designed for UWB applications. Two notched frequency bands are achieved by adjusting the E-shaped form lengths in the radiation patch. The proposed antenna operates in the 3.110.6 GHz for a voltage standing-wave ratio (VSWR) less than 2, except two frequency notched bands of 3.34.23 and 5.055.87 GHz, and has small overall dimensions of 18 x 15 x 1.6 mm3. Experimental and simulated antenna results show that the proposed antenna has a desirable VSWR level and radiation pattern characteristics for the UWB frequency band range.
