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: 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 method and apparatus are provided for operating a phased-array antenna (14) on a satellite-based communications node (10) in more than one mode by controlling the number of beam-forming elements and by applying appropriate phase-control and/or amplitude-control coefficients to the selected elements. The antenna can be operated as a diffused-beam antenna at a relatively low data rate, enabling the satellite-communications node (10) to communicate with a first terrestrial communications node (22). The antenna can also be operated to generate multiple focused-beam antenna patterns each communicating at a relatively high data rate, enabling the satellite-communications node (10) to communicate with a different terrestrial communications node (20) by changing the amplitude and/or the phase coefficients as well as the number of beam-forming elements.
