三陷波特性的超宽带单极子天线

内容简介：设计了一种具有三陷波特性的超宽带单极子天线。该天线通过在圆形贴片、馈线和接地板上引入半波长和四分之一波长的谐振电路,实现了三陷波功能,避免了与其他通信系统之间的干扰。通过仿真可知,天线的回波损耗带宽为1.88GHz～11.3GHz,陷波频段2.27GHz～2.60GHz,3.38GHz～4.12GHz和5.18GHz～5.93GHz,具有良好的辐射带宽和方向性。

Abstract：A kind of Ultra-Wideband（UWB） monopolar antenna with Triple Band-Not- ched function is presented. The antenna has triple band-notched function by using a half and a fourth wavelength resonant circuits, which are embedded in the circular patch, microstrip and ground patch. It can avoid interference with other communication systems. The simulation shows that the return loss waveband of the antenna is 1.85 GHz-11.3 GHz, the band-not- ched wavebands are 2.29 GHz-2.63 GHz, 3.36 GHz- 4.09 GHz and 5.03 GHz- 6.06 GHz,meanwhile,and the radition waveband and directivity are perfect.
