[Problem] To provide an antenna device which can rotate vertically and horizontally and has waveguides arranged efficiently therein. [Solution] An antenna device (1) provided with an antenna section (10), a vertical rotation section (35), and a rotary joint (34). The antenna section (10) can rotate vertically and horizontally, and radiates electromagnetic waves to the exterior. The lengthwise direction of the vertical rotation section (35) is arranged along the vertical-rotation axis line and so as to be perpendicular to the horizontal-rotation axis line. The rotary joint (34) is connected to the vertical rotation section (35). Also, the antenna device (1) has a waveguide channel which passes through the inside of the rotary joint (34) and the vertical rotation section (35), and is connected to the antenna section (10). |
