PROBLEM TO BE SOLVED: To provide a reception antenna device for receiving radiation power of satellite communication or satellite broadcast radiated from a stationary satellite which is a reception target, and a manufacturing method for a shaped reflector.SOLUTION: A reception antenna device 10 comprises: a shaped reflector 11; and a power feeding unit 12 for receiving a reception electric wave having radiation power reflected by the shaped reflector 11. A manufacturing method for the shaped reflector 11 comprises the steps of: arranging a gain constraint point by calculating a coordinates area determined by a stationary orbit viewed from a plurality of reception regions for a stationary satellite which is a reception target on a parabolic face having a fixed curvature; and giving a predetermined gain limit value for reducing an interference wave to the gain constraint point to correct a mirror shape of the parabolic face. |
