摘　　要：阐述了多模馈源的组成和工作原理,给出了多模馈源喇叭口径尺寸、主波导口径尺寸、次波导口径尺寸、喇叭口长度、主波导长度和次波导长度的计算公式,通过Matlab对五模馈源进行了数值仿真和分析,结果表明设计较好地解决了多模馈源的和差矛盾。The compositions and operating principle of Multimode feeds are discussed in this paper. The computing ex pressions for the size of horn aperture, the size of primary waveguide aperture, the size of secondary waveguide aperture, the length of horn, the length of primary waveguide and the length of secondary waveguide are provided. Fivemode feeds is em ulated and analyzed with Matlab. The simulation result shows the sumdifference inconsistency of Multimode feeds is prefer ably solved using the design of this paper.
