Abstract

Die Erfindung betrifft eine in einem Terminal für Systeme mit nichtgeostationären Satelliten zu verwendende Phased Array Antenne (2), mit der eine schnelle Schwenkung der Hauptkeule von einem Satelliten zu einem anderen Satelliten vorgenommen werden kann, in einer Ausführung als eindimensionale Antenne, die baulich auf einer mechanischen Schwenkvorrichtung (1) angeordnet ist. Die mit ihrer Hauptkeule nur in einer Schwenkebene abtastende Phased Array Antenne wird mittels der mechanischen Schwenkvorrichtung dabei stets so positioniert, daß die Schwenkebene (3) sowohl die beiden genannten Satelliten als auch das Terminal enthält. Während des Satellitenwechsels wird die Hauptkeule somit nur elektronisch geschwenkt.

Figure 00000001
The invention relates to a phased array antenna (2) to be used in a terminal for systems with non-geostationary satellites, with which the main lobe can be swiveled quickly from one satellite to another satellite, in a version as a one-dimensional antenna that is structurally based on a mechanical swivel device (1) is arranged. The phased array antenna, which only scans in one swivel plane with its main lobe, is always positioned by means of the mechanical swivel device so that the swivel plane (3) contains both the two satellites mentioned and the terminal. The main lobe is thus only pivoted electronically during the satellite change.
