摘要：
A compact dual band-notch ultra-wideband circle-like slot antenna fed by coplanar waveguide line is proposed.The U- and L-shaped slots are used to create dual-band notch characteristics. The antenna is as small as 26 x 26 x 1.6 mm3. The designed antenna offers a wide bandwidth from 2.75 to 14.2 GHz (135%), defined by VSWR < 2, with two notched bands, covering all the 5-/6-GHz WLAN, 3.5-/5.5-GHz WIMAX and 4-GHz C bands. An equivalent circuit model of the antenna is presented to discuss the mechanism of the dual band-notched UWB antenna. Impedance, radiation, and gain characteristics of the proposed antenna are also discussed. (C) 2012 Wiley Periodicals, Inc.
