Abstract
A reflector antenna, in particular for the reception and/or transmission of signals from and/or to satellites. The reflector antenna according to the invention comprises a reflector arrangement for focusing antenna radiation in a focal plane together with an antenna array arranged in the focal plane, or in the vicinity of the focal plane, with a plurality of antenna elements. A control device is provided with a beamforming means. Through the control device, sub-arrays, comprising one or a plurality of antenna elements of the antenna array for the reception and/or transmission of antenna radiation, can be activated and deactivated. In the operation of the reflector antenna, a radiation lobe pattern is formed by means of the beamforming means for the reception and/or transmission of antenna radiation for a particular activated sub-array.
