<正> 天线的方向性图有两类不同的优化目标,即参数优化和赋形优化,为获得最大增益,文献[1]借空气透镜的概念将平面口径改为双曲面形状,喇叭天线既可直接用作辐射器,又可用作反射面天线的照射器,应用于雷达、卫星通信和广播等场合都会遇到各种方向性图赋形的要求。以往关于曲面口径喇叭天线分析的物理光学法对口径面法向矢量的处理比较粗,当口径面曲率较大或口径面尺寸较大时会引起明显误差;几何射线法难以确定口径场分布对口径形状的依赖关系。本文对口径面法向矢量作了准确处理,并以方向性图赋形为目标对喇叭的曲面口径形状进行优化设计,采用驻相法减少计
Abstract:
The radiation pattern of the E-plane sectoral horn antenna with curved aperture is analyzed, and the optimization for the pattern shaping is studied. The method of stationary phase is used to calculate the diffraction integral and an improvement on the simplex method is proposed in order to accelerate the convergence. Some examples are given to verify the method.
