Abstract
An antenna device having a settable directional characteristic and a method for operating an antenna device. The antenna device according to the present invention includes a feed signal provision unit, with the aid of which a first, second, third and fourth electrical feed signal may be provided, the electrical feed signals being coherent with one another and having phases relative to one another which are adapted to set the settable directional characteristic of the antenna device, the phases being adaptable with the aid of a feed signal adaptation unit; a plurality of antenna columns, each antenna column including a respective plurality of electrically connected antenna elements; the electrical feed signals being conductable for inducing the antenna elements of the antenna columns to emit electromagnetic waves having the set directional characteristic.
