    • PROBLEM TO BE SOLVED: To improve mirror surface accuracy in an antenna reflector mounted on a satellite.SOLUTION: In this antenna reflector composed of a radio wave reflecting mirror surface, a rear structure disposed on the non-reflection surface of a radio wave reflecting sphere, and a coupling component for coupling the radio wave reflecting mirror surface and the rear structure, the shape of the radio wave reflecting mirror surface can be adjusted in a room temperature environment by coupling the rear structure to the coupling component by a bolt and a nut, and the shape of the radio wave reflecting mirror surface after the adjustment can be maintained by fastening the bolt and the nut while leaving them as they are. Thereby, the antenna reflector with improved mirror surface accuracy can be obtained.
    • 要解决的问题:提高安装在卫星上的天线反射镜的镜面精度。解决方案:在由无线电波反射镜面构成的天线反射镜中,设置在无线电波反射球的非反射面上的后结构 以及用于耦合无线电波反射镜面和后部结构的耦合部件,可以在室温环境中通过螺栓和螺母将后部结构耦合到联接部件来调节无线电波反射镜表面的形状 并且可以通过紧固螺栓和螺母而保持调整后的无线电波反射镜表面的形状,同时使它们保持原样。 由此,可以获得具有改善的镜面精度的天线反射器。
