An ultra‐wideband monopole antenna with water‐wave structure

A novel water-drop-shaped monopole antenna that is based on the model from nature is designed to realize ultra-wideband (UWB). Its UWB-related characteristics are simulated and experimentally verified. The results show that the proposed antenna has good radiation performances, which illuminates the structure is a good candidate for antenna design. Method of designing antenna using the model from nature will serve as a good candidate for the future antenna design. © 2011 Wiley Periodicals, Inc.
