| 摘 要： | 本文报道了圆锥波纹喇叭作为馈源系统的2.5m卡赛格伦天线的设计,修正其主、副面的形状,使该天线获得高效率(71.36％)、高增益(48.45dB)的效果.在给定初级馈源方向性图条件下,导出了使主面口径面获得均匀照射时主、副面修正的表达式.实践证明按这些表达式设计的2.5m卡氏天线是成功的.

| Abstract: | A high quality 2.5m Cassegrain antenna in a feed system of the conical corrugated horn has been designed by using a modification method of the special shaping of both mainreflector and subreflector.The theoretical expressions) which determine the shape of dual reflectors to give a uniform illumination of the mainreflectot for a given primary feed pattern are derived. Experimental results are presented. The efficiency of this antenna is 71.36%. The gain is 48.45db.These show that the design of this 2.5m Cassegrain antenna using these expressions is very successful. |
