摘　　要：讨论了我国Ku 波段广播通信卫星全国覆盖的赋形波束天线的设计问题。就我国目前的技术和工艺水平,提出了三种可行的方案;通过这三种方案,介绍了偏馈反射面天线的几何尺寸的选择,多波束天线的馈源位置排列及缋源幅相激励系数的优化步骤;最后绘制了三种方案的等值线覆盖图,分析和比较了它们各自的优缺点。A design method of contoured beam antenna covering all Chi- nese territory is described for Chinese communication satellite on Ku band. By considering available technique and technology level of China,three feasible conceptions are presented;with the three conceptions,how to select geometry dimensions of the offset parabolic reflector,how to arrange feed locations of multiple beam antenna and how to optimize amplitude and phase excitation coefficients of the feeds are discussed progressively;at last, contour coverage patterns of the three conceptions are shown,and the comparison of advantage and disadvantage among the three conceptions are made.
