摘要：
For the purpose of obtaining a mechanical drive reflecting mirror antenna device which is downsized and low in attitude, enables wide-angle scanning, and is high in performance, there are provided a main reflection mirror 1, a sub-reflection mirror 2, a primary radiator 3, a first circular waveguide 4 which is connected to the primary radiator and has a plurality of bend portions, a first circular waveguide rotary joint 5 which is connected to the first circular waveguide, a second circular waveguide 7 which is connected to the first circular waveguide rotary joint and has a plurality of bend portions, and a second circular waveguide rotary joint 8 which is connected to the second circular waveguide and is different in a direction of a rotary axis from the first circular waveguide rotary joint by substantially 90 degrees.
