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 3.1–10.6 GHz for a voltage standing‐wave ratio (VSWR) less than 2, except two frequency notched bands of 3.3–4.23 and 5.05–5.87 GHz, and has small overall dimensions of 18 × 15 × 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. © 2012 Wiley Periodicals, Inc.
