The present application discloses an antenna device provided with the following: first and second antenna elements for receiving and transmitting radio waves, a box body for accommodating a processing unit that performs signal processing in accordance with radio waves, and first and second element covers that accommodate the first and second antenna elements. The first and second element covers are held by the box body so as to be rotatable around first and second rotation axes, and include first and second rotation cylinders that protrude from the box body along the first and second rotation axes, and first and second protruding cylinders that protrude from the first and second rotation cylinders. Due to the rotation of at least one of the first and second rotation cylinders, a first narrow angle, stipulated between the first and second protruding cylinders, is changed. |
