Butterfly bionic antenna with ultra-wideband property
Xing Chen · Modern Electronics Technique · 2013
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|S1 1 |-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.
