摘要
基于仿生学原理，仿生天线能够在获得良好天线性能的同时，兼顾天线外形美观或隐蔽性。模仿蝴蝶外形，设计了一款具有超宽带特性的印刷微带单极子天线，并加工制作。该天线外观酷似蝴蝶，测试表明该天线的｜S11｜〈-10dB的阻抗带宽达到了107％（3．2-10．6GHz），天线具有全向辐射特性，天线尺寸仅为26mm×27．8mm×1mm。
Bionic antennas based on bionics principle not only are able to achieve good antenna performances, but also possess beautiful shapes or concealed property. In this paper, a printed microstrip monopole antenna with uhra-wideband （UWB） property was designed by mimicking the shape of a butterfly. This antenna was fabricated and measured. It has a butterfly-like appearance. The measurement results that its ｜S11｜〈- 10 dB impedance bandwidth reaches 107% （3.2-10.6 GHz）, and the antenna has the omnidirectional radiation characteristics. The size of the antenna is only 26 mm×27.8 mm×1 mm.
