Abstract
An antenna device vertically rotatable and horizontally rotatable is provided, which has a configuration in which waveguides are effectively disposed. An antenna device includes an antenna, a vertically rotating, and a rotary joint. The antenna is vertically rotatable and horizontally rotatable, and outwardly radiates a radio wave. The vertically rotating is disposed such that a longitudinal direction thereof is along an axial line of the vertical rotation and intersects perpendicularly with an axial line of the horizontal rotation. The rotary joint is coupled to the vertically rotating. Moreover, the antenna device includes a waveguide path passing through the inside of the rotary and the inside of the vertically rotating and connected with the antenna.
