Claims

[Scope of utility model registration request]

first, second, and third ducts each having a bent shape, the interior of which is pierced by a cavity, and a first turn coupling between one end of the first duct and one end of the second duct; a wheel bearing, and a rotating shaft that is perpendicular to the first rotational bearing and that connects the other end of the second duct and one end of the third duct, is placed in a substantially vertical direction; two slewing ring bearings, first and second drive mechanisms that respectively drive the first and second ducts around the rotation axes of the first and second slewing ring bearings, and the first and second ducts. a curved reflecting mirror fixed inside a bent portion of any one of the second and third ducts;
and the third duct, a total of two plane reflectors each fixed inside the bent part of the other two ducts, and the body part of the automatic vehicle to which the third duct is fixed, or a primary radiator fixed to the container on the vehicle body so as to protrude from the vehicle body portion or the container on the vehicle body and extending to the interior of the third duct; and the other end of the first duct. a beam waveguide formed by the curved reflector ♂ and the two plane reflectors and the primary radiator; A vehicle-mounted antenna device in which the bending angles of each of the beams are selected to be 90 degrees.
