Patent number: 8190085Abstract: A method for communication includes transmitting first and second copies of a signal toward first and second satellite transponders, respectively, so as to cause the first and second satellite transponders to transmit respective first and second downlink signals with mutually-orthogonal linear polarizations toward a coverage region. A correction is applied to at least one of the first and second copies before transmitting the first and second copies. The correction is selected so as to remove a frequency offset between the first and second downlink signals and cause the first and second downlink signals to have a constant phase offset in at least some of the coverage region.Type: GrantFiled: November 26, 2009Date of Patent: May 29, 2012Assignee: AT&T Intellectual Property I, L.P.Inventors: Ilan Barak, Danny Spirtus

Publication number: 20110215985Abstract: 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.Type: ApplicationFiled: February 18, 2011Publication date: September 8, 2011Applicant: RAYSAT ANTENNA SYSTEMS, L.L.C.Inventors: Ilan Kaplan, Mario Ganchev Gachev, Moshe Bercovich, Danny Spirtus, Daniel Francis DiFonzo, Kevin Arthur Bruestle, Robert Yip, Victor Boyanov, Yoel Gat, Stanimir Dimitrov Kamenopolski

Publication number: 20060199543Abstract: A test system and method for indoor testing of a mobile antenna terminal having a first antenna with a first aperture of a first size and, preferably, operable in a receive-only mode and/or a transmit and receive mode. The system uses a second antenna having a dual port feed and a reflector, the second antenna having a second aperture of a second size, which is two or more times the first size, and being operative to form a plane wave. The first antenna is mounted to a test platform that is positioned within the second aperture and is operative for rotating and tilting movement of the antenna to simulate movement on a vehicle. The test system uses a source of RF test signals and communications test equipment coupled to at least the first antenna, as well as a processor for determining a performance of the mobile antenna terminal.Type: ApplicationFiled: March 4, 2005Publication date: September 7, 2006Inventor: Danny Spirtus
