Publication number: 20220021111Abstract: A multi band antenna system for transmission and reception of electromagnetic signals in a low-profile dual reflector configuration with position-controlled main-reflector, and fixed sub-reflector and feed horn. An added linear slide of the main-reflector with respect to the sub-reflector synchronized with variable tilt angle of the main-reflector for compensation for the varied focal length in the main-reflector to the beam due the varied main-reflector tilt. The system achieves a beam elevation of 10° to 100° (full elevation), minimum gain variations over the full elevation travel, swept volume as per ARINC 791 (e.g. Boeing Radome or Airbus Radome), and can be used to meet wide-Tx/Rx bands requirements.Type: ApplicationFiled: November 10, 2019Publication date: January 20, 2022Inventors: Guy NAYM, Ladislav RUDMINSKY, Alon LEIB, Binyamin LAUFER, Hanan KEREN, Itzik KREPNER, IIan HALEVI

Patent number: 9960861Abstract: A system for measuring blockage facilitates automated measuring using an installed antenna as a measuring device, providing more accurate and reliable results as compared to conventional methods of measuring blockage. The system eliminates the need for meticulous and tedious manual measurements as well as the time consuming search for structural drawings, necessary to perform conventional blockage measuring. The system features an efficient and accurate way of establishing the angular direction points in which an antenna view is obstructed by recording the obstruction reflections standing out of the clear sky noise floor. Embodiments are particularly useful when installing a satellite communications antenna on a ship having metal structures obstructing the antenna's view such as communication masts, funnels, and smokestacks.Type: GrantFiled: February 1, 2016Date of Patent: May 1, 2018Assignee: ORBIT COMMUNICATION SYSTEMS LTDInventors: Azriel Yakubovitch, Miron Voin, Stav Gizunterman, Guy Naym

Patent number: 9711850Abstract: Control of dual (two) antennas, for satellite communications (satcom) with satellites in one or more constellations in Low Earth Orbit (LEO) and Medium Earth Orbit (MEO). The dual antennas are typically part of a ground-based antenna system, in particular using the Satrack single pedestal with split antenna design, housed efficiently under a compact radome. Features simultaneous pointing toward two separate satellites during the satellites' handover/switching periods with instantaneous transition between the satcom modems for assuring real-time, continuous data communication over a LEO/MEO satellite link. The dual (two) antennas system can also be used in a “monopulse/electronic scan” mode where a first antenna is used for tracking according to ephemeris data, while a second antenna on the same pedestal will scan for offset/compensation to the first antenna path.Type: GrantFiled: December 8, 2015Date of Patent: July 18, 2017Assignee: ORBIT COMMUNICATION SYSTEMS LTDInventors: Guy Naym, Hanan Keren, Michael Greenspan, Azriel Yakubovitch, Miron Voin, Stav Gizunterman

The system eliminates the need for meticulous and tedious manual measurements as well as the time consuming search for structural drawings, necessary to perform conventional blockage measuring. The system features an efficient and accurate way of establishing the angular direction points in which an antenna view is obstructed by transmitting a test signal from a transmitter horn in a transmitting direction and receiving a reflection of the test signal at an installed antenna in a receiving direction, wherein the transmitting direction is directionally aligned with the receiving direction. Embodiments are particularly useful when installing a satellite communications antenna on a ship having metal structures obstructing the antenna's view such as communication masts, funnels, and smokestacks.Type: ApplicationFiled: February 1, 2016Publication date: August 4, 2016Inventors: AZRIEL YAKUBOVITCH, Miron VOIN, Stav GIZUNTERMAN, Guy NAYM

Patent number: 8994473Abstract: A waveguide has distal, medial and proximal sections. The distal and medial sections rotate relative to each other and to the proximal section. In a first configuration, the waveguide transforms linearly polarized electromagnetic radiation at the proximal end of the proximal section to linearly polarized electromagnetic radiation at the distal end of the distal section and vice versa. In a second configuration, the waveguide transforms linearly polarized radiation at the proximal end of the proximal section into circularly polarized electromagnetic radiation at the distal end of the distal section and vice versa. Preferably, the distal and medial sections include respective eight-wavelength polarizers and the proximal section includes a quarter-wavelength polarizer. A multi-band antenna feed includes two such waveguides, one nested inside the other, for transforming electromagnetic radiation of respective frequency bands.Type: GrantFiled: December 28, 2011Date of Patent: March 31, 2015Assignee: Orbit Communication Ltd.Inventors: Guy Naym, Hanan Keren, Izik Krepner, Shiomo Levi

Patent number: 8648748Abstract: An effective marine stabilized antenna system, in terms of antenna to radome size and antenna/RF performance complies with all relevant worldwide SatCom regulations. The combination of a dual offset Gregorian antenna (DOGA) with a stabilized polarization over elevation over tilt over azimuth pedestal, and a control/stabilization algorithm, ensures antenna orientation restrictions guarantee compliance with side-lobe intensity regulations. Operating a dual offset Gregorian antenna substantially within a pre-determined antenna cut range of a 45 degree angle relative to a configuration of the antenna and a relative position of a target provides antenna performance that complies with applicable SatCom regulations, despite having to flip the antenna 90 degrees to continue tracking the satellite.Type: GrantFiled: February 13, 2011Date of Patent: February 11, 2014Assignee: Orbit Communication Ltd.Inventors: Azriel Yakubovich, Guy Naym, Idan Fogel, Ervin Rozman, Shlomo Levi, Michael Greenspan, Moshe Gvili, Or Dadush, Benny Ben Rey

Publication number: 20110057849Abstract: A ground station antenna includes a LNB with at least one dipole, a feed horn, a waveguide between the LNB and the feed horn, and a rotation mechanism. By rotating a portion of the waveguide, the polarization of an electromagnetic wave propagating between the LNB and a satellite is transformed to match the polarization to (one of) the dipole(s) and to an antenna on the satellite. Another ground station antenna includes a main waveguide, two mutually orthogonal branch waveguides, a coupling mechanism for coupling two orthogonal antenna dipoles to the proximal end of the waveguide, and a transformation mechanism that transforms the polarization of an electromagnetic wave propagating between the branch waveguides and a satellite via the antenna dipoles to match the polarization to one of the branch waveguides and to an antenna on the satellite.Type: ApplicationFiled: September 8, 2009Publication date: March 10, 2011Applicant: ORBIT COMMUNICATION LTD.Inventors: Guy NAYM, Hanan KEREN

Patent number: 6608590Abstract: A method for aligning an antenna polarization axes of a dual polarized end-user terminal having an antenna. The antenna is aligned with a satellite in relation to azimuth and elevation. The end-user terminal is configured in an alignment mode to produce a first output corresponding to a first component of a received signal parallel to a first polarization axis of the antenna and a second output corresponding to a second component of the received signal parallel to a second polarization axis of the antenna. The first polarization axis is orthogonal to the second polarization axis. The method includes the steps of: receiving a linearly polarized signal; autocorrelating the first output and the second output to produce a measurement of autocorrelation; and adjusting the antenna polarization axes to minimize the measurement of autocorrelation.Type: GrantFiled: March 4, 2002Date of Patent: August 19, 2003Assignee: Orbit Communication Ltd.Inventors: Guy Naym, Hanan Keren
