Zusammenfassung:An antenna element includes a reflector plate and a radiator comprising a balun device and a dipole device for operating in a first frequency band. The dipole device is connected to the reflector plate by the balun device. A distance from the dipole device to the reflector plate is more than ¼ of a wavelength at a central frequency of the first frequency band. The balun device comprises a short-circuit at a distance from the dipole device of 15 to 35 percent of said wavelength.
