摘　　要：通过对介质透镜赋形,把初级馈源方向图转变为透镜口径面上所需的场分布函数,便可获得所需要的各种波束。本文给出了一种基于几何光学的简单而实用的透镜赋形方法,通过赋形能实现介质透镜天线低副瓣的要求。Shaping techniques are applied to the design of dielectric lens antennas.The aim of shaping is to find a lens profile that transforms the radiation pattern of the primary feed into a desired amplitude shaped output pattern.This paper presents a flexible shaping approach that based on geometrical optics(GO),by shaping,the lens antenna can achieve low side-lobes.
