More Information
Summary: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.
