1. An antenna device, for a mobile body, comprising:
an antenna configured to be installed in the mobile body; and
a reflector having a reflection surface configured to change a beam direction of the antenna,
wherein the antenna includes
a plurality of first antenna elements configured to generate a first beam, and
a plurality of second antenna elements configured to generate a second beam, and
the reflection surface includes a first reflection region configured to direct the first beam toward a first direction, and
a second reflection region configured to direct the second beam toward a second direction different from the first direction, and
the first antenna elements and the second antenna elements are disposed such that the first beam and the second beam are directed toward a same direction between the antenna and the reflector,
the plurality of first antenna elements are disposed in a row in a direction parallel to the first reflection region, and
the plurality of second antenna elements are disposed in a row in a direction parallel to the second reflection region.
