PROBLEM TO BE SOLVED: To provide a space synthesis antenna device and manufacturing method for a modified mirror surface reflector, that enable a radiation power pattern to vary.SOLUTION: A space synthesis antenna device 10 of the present invention comprises: a phased array power supply unit 13 comprising a plurality of radiation elements 14 arranged in a regular manner whose radiation gain is classified into 3 or less types; and a modified mirror surface reflector 11 in a fixed shape which spatially synthesizes radiation beams radiated from a plurality of radiation elements 14 and forms a predetermined radiation power pattern. A manufacturing method for the modified mirror surface reflector 11 comprises a step of inspecting whether or not radiation gain in a specific region in a service area can be changed within a predetermined range by controlling an excitation amplitude value and excitation phase value of the radiation element 14, while modifying and optimizing a mirror surface shape of a modification reference parabolic surface in relation to the modified mirror surface reflector 11 so that a radiation power pattern obtained by spatially synthesizing radiation beams radiated from the plurality of radiation elements 14 achieves a target gain value. |
