Abstract
There is disclosed an antenna apparatus used for satellite communication or the like and including an antenna rotating in an azimuth angle direction and an elevation angle direction, which can be miniaturized without using a slip ring for ensuring electrical connection between a stationary portion and a movable portion. A rotary member is rotated by rotation of a motor to rotate an antenna about an azimuth axis. On the other hand, a motor is rotated to rotate a rotary member and a relative rotary shaft is rotated by relative rotation between the rotary member and the rotary member The rotation of the relative rotary shaft rotates the antenna about an elevation angle axis by rotation transmission through a bevel gear and a bevel gear
