<P>PROBLEM TO BE SOLVED: To solve the following problem: a radio wave reflection mirror plane of an antenna reflector installed on an artificial satellite uses a composite material formed from carbon fiber or the like in view of weight reduction, radio wave reflection properties and shape stability, and when the composite material is employed for a radio wave reflection mirror plane, a process for hardening resin under a semi-cured state in the manufacturing process is required; however, in the curing process, the mirror plane precision of the reflector is generally deteriorated because molding distortion is generated in the composite material. <P>SOLUTION: A radio wave reflective member is mounted at a generation position of molding distortion of a radio wave reflection mirror plane by a hardening process. The mounting of the radio wave reflective member is implemented by adhesive fixing, fiber bundle sewing or by other means. By locally disposing the radio wave reflective member, the shape of the radio wave reflection mirror plane is corrected to provide an antenna with high mirror plane precision. <P>COPYRIGHT: (C)2012,JPO&INPIT |
