摘要
A novel smiling-face-shaped band-notched ultra-wideband (UWB) antenna is designed in this paper. First, antenna bandwidth is broadened by adding a pair of small semi-circular stubs (ears) and etching a pair of symmetrical C-shaped slots (eyes), a triangular slot (nose), and a U-shaped slot (mouth) on the patch. Second, by adjusting the length of the ground plane and creating a stepped slot on the ground plane, antenna bandwidth covers 3-12 GHz. Third, a pair of L-shaped slots (hands) is etched on the ground plane to create a notch, which can effectively suppress the interference signal in worldwide interoperability for microwave access (WiMAX) (3.4-3.6 GHz) and satellite C band (3.7-4.2 GHz). Lastly, the proposed antenna is fabricated and measured. The measured results indicate the proposed antenna has good performance and can be widely used in UWB systems.
