提出了利用渐变槽线天线物理截面小的特点与变极化技术相结合的方法来改善微带反射阵馈源的遮挡效应,并设计了用于变极化微带反射阵馈源的渐变槽线天线及含37单元的微带反射阵。鉴于这些特点,该类天线在雷达、移动通信等领域具有潜在工程应用。文中给出了部分的理论分析和实例佐证。

A new method to improve the blockage of microstrip reflectarray feeder is proposed,which makes use of the small physical section of tapered slot antenna and is combined with polarization transform technique.Then the tapered slot antenna acts as the feeder and the microstrip reflectarray with variable polarization consisting of 37 elements are presented.Dueto these ad- vantageous features,this kind of antenna has potential significance for engineering applications in radar,communication,and etc. In this papar,the theoretical analysis is presented and a specific design sample is provided to verify this method.
