Antenna device and method for operating an antenna device

A method for operating an antenna device, which comprises an antenna array having at least two transmission devices in first predeterminable positions and having at least two receiving devices in second predeterminable positions, the method comprising:

• exciting the at least two transmission devices alternately, 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;
• and
• exciting the at least two transmission devices in joint 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,
• wherein 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.

A non-transitory computer readable medium having stored thereon a program element for operating an antenna device, which comprises at least two transmission devices in first predeterminable positions and having at least two receiving devices in second predeterminable positions, which, when it is executed by a processor, carries out the following method, comprising:

• exciting the at least two transmission devices alternately, 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;
• and
• exciting the at least two transmission devices in joint 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,
• wherein 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.
