Patent number: 10637152Abstract: A polarizing reflector for broadband antennas includes a flat dielectric substrate, a patch array layer formed by a bi-dimensionally periodic lattice of thin metallic patches along first and second perpendicular directions x, y, and a ground layer. All the patches have a same shape elongated along the second direction y and form electric dipoles when electrically excited along the second direction y. For each row the patches of the said row are interconnected by an elongated metallic strip oriented along the first direction x and having a width c.Type: GrantFiled: September 7, 2018Date of Patent: April 28, 2020Assignee: THALESInventors: Hervé Legay, George Goussetis, Wenxing Tang, Daniele Bresciani, Renaud Chiniard, Nelson Fonseca

Patent number: 9647336Abstract: A radiating phase-shifting cell is designed to favour the excitation of an equivalent resonance of the “slot” type in a first part of the phase cycle, and to favour an equivalent resonance of the “microstrip” type in a second part of the phase cycle. This property notably allows the bandwidth of the phase-shifting cells to be optimized. A phase range of 360° can in effect be segmented into two sub-ranges of around 180°. This segmentation into two sub-ranges is made possible by the complementarity of the resonant modes of the slot or microstrip type. The radiating phase-shifting cell is notably applicable to reflector arrays for an antenna designed to be installed on a space craft such as a telecommunications satellite or on a terrestrial terminal for satellite telecommunications or broadcasting systems.Type: GrantFiled: September 14, 2012Date of Patent: May 9, 2017Assignees: Thales, Institut National Des Sciences Appliquees De Rennes, Centre National De La Recherche ScientifiqueInventors: Herve Legay, Etienne Girard, Daniele Bresciani, Raphael Gillard, Hassan Salti, Tony Makdissy, Erwan Fourn

Patent number: 9112281Abstract: A reflector array antenna with cross-polarization compensation including at least one radiating element having an etched pattern dissymmetric with respect to at least one direction X and/or Y of the plane XY of the radiating element, the dissymmetry of the pattern of the radiating element being calculated individually on the basis of a radiating element of the same symmetric pattern along the two directions X and Y, so as to engender a reflected wave having a controlled depolarization which opposes a depolarization, engendered in a plane normal to a direction of propagation, by the reflector array illuminated by a primary source.Type: GrantFiled: February 11, 2011Date of Patent: August 18, 2015Assignee: THALESInventors: Daniele Bresciani, Hervé Legay, Gérard Caille, Eric Labiole

Patent number: 8319698Abstract: A reflector array comprises a plurality of individual radiating elements forming a reflecting surface with no abrupt transitions wherein each radiating element of the reflecting surface is selected from a set of predetermined consecutive radiating elements, called the pattern, the first and last elements of the pattern correspond to one and the same phase, modulo 360°, and are identical, and the radiating elements of the pattern have a radiating structure, of metal patch type and/or of radiating aperture type, that progressively changes from one radiating element to another adjacent radiating element, the change in the radiating structure comprising a succession of progressive growths of at least one metal patch and/or at least one aperture and appearances of at least one metal patch in an aperture and/or at least one aperture in a metal patch.Type: GrantFiled: October 5, 2009Date of Patent: November 27, 2012Assignee: ThalesInventors: Hervé Legay, Danièle Bresciani, Renaud Chiniard, Etienne Girard

Patent number: 8248306Abstract: A dual-polarization planar radiating element having an external metal grid, at least one metal patch concentric with the external metal grid and a cavity separating the metal grid and the metal patch, the grid and the patch having a polygonal shape delimited by at least four pairwise opposite sides, and two orthogonal directions of polarization associated with two orthogonal electric fields Ev and Eh, at least one of the directions of polarization being parallel to two sides of the polygon. Each side of the metal patch parallel to a direction of polarization is linked electrically to a zone of the external grid where one of the electric fields Ev or Eh is a minimum. The invention exhibits the advantage of reducing the phenomenon of electrostatic discharges in the planar radiating elements without significantly modifying the response of the radiating element subjected to an orthogonally polarized wave.Type: GrantFiled: October 14, 2009Date of Patent: August 21, 2012Assignee: ThalesInventors: Herve Legay, Daniele Bresciani, Renaud Chiniard

Patent number: 4835087Abstract: A method of manufacturing dichroic antenna structures, which makes use of a projector mounted on the mobile arm of a computer-controlled machine to project the shape of selective antenna elements on the surface of an insulating layer, clad with a metallic layer covered in turn with a photographic emulsion. Development and chemical etching of the excess conductive parts are then carried out.Type: GrantFiled: July 30, 1987Date of Patent: May 30, 1989Assignee: Cselt-Centro Studi E Laboratori Telecomunicazioni SpaInventors: Paolo Bielli, Daniele Bresciani, Salvatore Contu, Giuseppe Cocito
