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. © 2016 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
