A circular wide-slot UWB antenna with dual band-notched characteristics is proposed in this paper. The microstrip-fed antenna mainly consists of a calabash-shaped feeding patch and a metal ground with a circular slot etched. Dual notched bands are realized by introducing arc-shaped parasitic strip and slot on the ground plane. The measured results show that the proposed antenna can operate at the range of 2.91-11.45 GHz with VSWR < 2 for UWB applications, except the notched bands of 3.38-3.71 GHz and 5.39-6.27 GHz for the 3.5 GHz WiMAX and 5.8 GHz WLAN, respectively.
