1. An antenna device, comprising:

  • a controller; and

    an antenna array comprising;

    at least two transmission devices in first predeterminable positions,at least two receiving devices in second predeterminable positions,wherein the controller is configured to alternately individually excite the at least two transmission devices for transmission in such a way that each of the at least two receiving devices receives a first transmitted signal generated by each of the at least two transmission devices,wherein the controller is further configured to excite the at least two transmission devices jointly for transmission at a predeterminable moment, in such a way that each of the at least two receiving devices receives a second transmitted signal generated by a single virtual transmission device, andwherein the virtual transmission device is arranged in a predeterminable position which differs from the first predeterminable positions of the at least two transmission devices; and

    wherein, when the at least two transmission devices are adjacent, the first predeterminable positions of the at least two transmission devices are arranged at a distance which is less than or equal to half a wavelength of used signals and/or when the at least two receiving devices are adjacent, the second predeterminable positions of the at least two receiving devices are arranged at a distance which is less than or equal to half the wavelength of used signals.
