Abstract
The invention concerns a satellite antenna system, especially for voice communication, designed for a moveable land station, which includes an antenna unit 1', which can be aimed at the satellite in the azimuth plane. According to the invention, the satellite antenna system includes a number of antenna elements 1; 1 superscript 1 - 1 superscript 12, from which the antenna unit 1' is formed, a control unit 4 and a coupling unit 5, the antenna elements of the antenna unit being arranged side by side on a circular periphery and of these antenna elements, two antenna elements side by side belong to the same active antenna unit 6, being selected by means of the control unit and the connection unit so as to receive and send circularly polarised electromagnetic radiation from a desired direction, in essentially the same direction. <IMAGE>
