具有双陷波特性的小型Vivaldi超宽带天线
|
摘要
设计了一种具有双陷波特性的小型化Vivaldi天线。通过在天线的辐射贴片上开一对E字型结构和在馈电处开电容性负载环路(capacitively loaded loop,CLL)结构,可以有效滤除无线局域网(wireless local area networks,WLAN)(5.15~5.825GHz)、卫星X波段(7.25~7.75GHz)的干扰。天线的工作带宽为3.3~12.8GHz,天线结构简单紧凑,具有非常小的尺寸,仅为26mm×13mm×0.762mm。从天线的表面电流方面,解释了天线的陷波原理,并且加工了天线实物。实测的驻波比、增益和方向图与仿真结果一致,验证了该天线在超宽带波段内具有良好的陷波特性、增益特性和全向性,可以应用于小型化超宽带系统中。该天线对于设计陷波Vivaldi天线也具有一定的指导意义。
A compact Vivaldi antenna with dual band-notched characteristics is proposed.By etching apair of E-shaped structures and capacity loaded loop(CLL)on the radiation patch of the antenna,it can effectively filter out the interference of wireless local area networks(WLAN)(5.15-5.825 GHz)and satellite X band(7.25-7.75 GHz).The working bandwidth of the antenna is 3.3-12.8 GHz and the antenna structure is simple and compact with a very small size,only 26 mm×13 mm×0.762 mm.The principle of the notch is explained from the surface current of the antenna and the antenna object is fabricated.The measured voltage standing-wave ratio(VSWR),gain and radiation pattern are consistent with the simulated results.The results show that the antenna has good notch characteristics,gain characteristics,is omnidirectional in the ultra-wideband band,and can be applied to the miniaturized ultra-wideband system.The antenna also has a certain guiding significance for designing the notched Vivaldi antenna.
