PURPOSE:To obtain an economical antenna reflectng mirror with improved electric performance by providing in parallel m sets of reflecting mirror elements having a reinforcement aggregate section formed integrally with a reflecting plane element divided, fixing them with a mounting frame to form a reflecting mirror assembly, and combining n sets of the assemblies. CONSTITUTION:The antenna reflecting mirror is divided into nXm sets of mirrors radially along the circumferential direction, m sets of the reflecting mirror elements 6 having the reinforcement aggregate sections 61-64 formed integrally with the reflecting plane elements 65 divided in this way are provided in parallel, and the reflecting mirror elements 6 are fixed by the mounting frame 7 to form the reflecting mirror element assembly 10. Then, n sets of the reflecting mirror element assemblies 10 are manufactured and they are combined in parallel. Thus, the antenna reflecting mirror with low cost, large mechanical strength, also high accuracy and improved electric performance is obtained. |
