Abstract: A phased-array antenna with electronic beam steering that provide simultaneous operation at transmit and receive frequencies and polarization control is disclosed. The antenna architecture reduces the number of beam steering and polarization control devices used compared to conventional array designs. The extremely compact, low-loss, and largely passive design reduces the number of active amplifiers needed using micro-electromechanical systems MEMs and advanced micro-coaxial circuits.

Abstract: A multi-band low-profile, low-volume two-way mobile panel array antenna system is described. Operation of the antenna may automatically switch between bands based on various user-entered parameters.

Abstract: Antenna and satellite communications assemblies and associated satellite tracking systems that may include a low profile two-way antenna arrangement, tracking systems, and applications thereof. Applications for the system include military, civilian, and domestic emergency response applications. The antenna arrangements may be configured to form a spatial multi-element array able to track a satellite in an elevation plane by electronically dynamically targeting the antenna arrangement and/or 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 system provides autonomous dynamic tracking of satellite signals and can be used for satellite communications on moving vehicles in a variety of frequency bands for military and civilian applications.

Abstract: A low profile mobile in-motion antenna and transmit/receive terminal system for two-way “VSAT” type satellite communication using FSS service, preferably in Ku band, supporting at the same time TV signal reception from the same satellite or a separate DBS satellite located at the same or nearby geo-stationary orbital position.

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. The system provides dynamic tracking of satellite signals and can be used for satellite communications on moving vehicles.
