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<-10 dB的阻抗带宽达到了107%(3.2~10.6 GHz),天线具有全向辐射特性,天线尺寸仅为26 mm×27.8 mm×1 mm.

Bionic antennas based on bionics principle not only are able to achieve good antenna performances,but also pos?sess beautiful shapes or concealed property. In this paper,a printed microstrip monopole antenna with ultra?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 anten?na has the omnidirectional radiation characteristics. The size of the antenna is only 26 mm×27.8 mm×1 mm.
