摘要
以提高Vivaldi天线的增益为目的,利用CST仿真软件设计了一种工作在3.7~14 GHz的3D超宽带、高增益的Vivaldi天线。该天线在传统Vivaldi天线的基础上引入开槽设计,并由两个相邻的Vivaldi天线组成,旋转角度为180°,具有三维弯曲结构的特点。馈电结构采用微带线槽线馈电,以更好地完成阻抗匹配。在工作频带内增益达到10 dBi,平均效率为95.2%,可以工作在C波段、X波段和部分Ku波段,适用于微波成像及双边方向的基站。
In order to improve the gain of Vivaldi antenna,a 3D ultra-wideband,high-gain Vivaldi antenna that works at 3.7~14 GHz is designed using the CST simulation software.The antenna introduces a slotted design on the basis of the traditional Vivaldi antenna and is composed of two adjacent Vivaldi antennas,with a rotation angle of 180°,and it has the characteristics of a three-dimensional curved structure.The feed structure adopts microstrip line-slot line fed to better complete impedance matching.The gain reaches 10 dBi in the working frequency band and the average efficiency is 95.2%.It is suitable for microwave imaging and bilateral base stations.
