摘　　要：首先针对相同口径的环焦天线主反射面通用化需求,对双反射面天线的发展背景和环焦天线优点及赋形机理进行了简要介绍,然后提出了一种在不改变环焦天线的主反射面曲线的基础上,改变馈源照射角和重新赋形环焦天线副反射面曲线的设计方法,最后依据提出的设计方法给出了设计仿真计算,计算结果满足工程需求,避免了天线主反射面重新开模具,实现了环焦天线主反射面通用化,大大降低了天线的生产成本。Firstly,aiming at the commonality requirement for the main reflector of the ring-focus antenna with equal diameter, the development background of dual-reflector antenna and the advantage and shaped principle of the ring-focus antenna are simply introduced.Secondly, the design method of changing illumination angle of feed source and new shaped subreflector curve for shaped ringfocus antenna is presented without changing the main-reflector curve of ring-focus antenna.Finally,the simulation calculation is given by the above design method.The design results can meet the requirements of the project.The mould of main reflector is avoided making again.The commonality of main reflector of ring-focus antenna is realized and the production cost of antenna is significantly reduced.
