Abstract: Antenna system that includes a plurality of antenna arrangements, each having one or more ports, and all ports connected through transmission lines in a combining/splitting circuit. The antenna arrangements form a spatial phased array able to track a satellite in an elevation plane by mechanically rotating the antenna arrangements about transverse axes giving rise to generation of respective elevation angles and changing the respective distances between the axes in a predefined relationship with the respective elevation angles. The combining/splitting circuit provides phasing and signal delay in order to maintain pre configured radiating parameters. The arrangements can be mounted on a rotating platform to provide azimuth tracking. The system provides dynamic tracking of satellite signals and can be used for satellite communications on moving vehicles.

Abstract: Antenna assembly for satellite tracking system that includes a plurality of antenna arrangements, each having one or more ports, and all ports connected through transmission lines in a combining/splitting circuit. The antenna arrangements form a spatial element array able to track a satellite in an elevation plane by mechanically dynamically rotating the antenna arrangements about transverse axes giving rise to generation of respective elevation angles and dynamically changing the respective distances between the axes whilst maintaining a predefined relationship between said distances and the respective elevation angles. The combining/splitting circuit provides phasing and signal delay in order to maintain pre configured radiating parameters. The arrangements can be mounted on a rotating platform to provide azimuth tracking.

Abstract: A method for scanning of antenna array, wherein on output signals from radiating elements are applied phases offset in order to obtain signals with approximately equal phases. The obtained signals are subsequently summated. The method is characterized in that before application of phase control the output signals from radiating elements are grouped by means of summation of the signals with approximately equal phases in order to form equivalent group signal. Subsequently the phase offset is applied on all group signals and subsequently all group signals are summated.
