Abstract
An antenna device includes a plurality of antenna elements. Each of the plurality of antenna elements outputs radio signals transmitted to another antenna device arranged so as to be opposed to the antenna device. At least one of the plurality of antenna elements is configured in such a way that a polarization direction of the radio signals to be output can be switched between a first direction and a second direction that is orthogonal to the first direction.
