摘要：
A novel compact coplanar waveguide-fed planar monopole ultra-wideband (UWB) antenna with 3.5/5.4 GHz dual band-notched functions is proposed in this article. To minimize the electromagnetic interferences between WiMAX/WLAN and UWB, a pair of inverted U-shaped slots is etched in the center of the radiation element. The proposed UWB antenna achieves a wide band of 3-10.6 GHz for the VSWR less than 2, except the notched bands of 3.16-3.85 GHz and 4.96-5.82 GHz. Furthermore, a nearly omni-directional radiation pattern and a stable gain ranging from 2.8 to 5.8 dBi are obtained except the rejected frequency bands. (C) 2012 Wiley Periodicals, Inc.
