Patent number: 10741897Abstract: A matched horn coupler assembly is used in a RF rotational joint for conveying an electromagnetic signal. The coupler assembly includes first and second feed horns defining respective first and second horn longitudinal axes intersecting one another at an intersection point. The first and second feed horns connect to a mirror for conveying the signal there between with the intersection point lying on a reflecting surface of the mirror which defines a normal direction thereof at the intersection point. The normal direction is equally angularly spaced from both the first and second horn longitudinal axes. First and second lenses connect to the respective first and second feed horns and focus the signal there between and at the intersection point. At least one of the first and second feed horns is rotatably connected relative to the mirror about the respective horn longitudinal axis.Type: GrantFiled: August 29, 2018Date of Patent: August 11, 2020Assignee: MACDONALD, DETTWILER AND ASSOCIATES CORPORATIONInventors: Eric Darnel, Philippe Loiselle, Yan Brand

Patent number: 9641135Abstract: A method for detecting an unbalance of a multi-port amplifier MPA intended to be on-board a satellite is presented. The MPA includes a plurality of paths, each path being configurable in gain and phase. The method includes transmitting a first test signal which is spread spectrum modulated from the first transmitting station to the first pathway, the first test signal being generated in at least the useful band of the first pathway; receiving by the second receiving station configured in frequency to receive signals transmitted by the second antenna connected to the second path of the MPA, the signals being likely to include a replica of the first test signal; detecting and measuring a power of received signals corresponding to a replica of the first test signal having leaked at the output of the second output port; computing at least one unbalance value of the MPA from the measurement of the power of the replica of the first test signal received in the second earth station.Type: GrantFiled: March 4, 2015Date of Patent: May 2, 2017Assignee: EUTELSAT S AInventors: Antonio Arcidiacono, Daniele Vito Finocchiaro, Alessandro Le Pera, Yan Brand

Patent number: 7236142Abstract: An electromagnetic bandgap device is mountable on a RF disturbing structure of an antenna to minimize signal field disturbance imparted thereby. The RF disturbing structure is oriented in a direction substantially parallel to a path of travel of an antenna signal and located within a field covered by the signal transmitted by a feed. The bandgap device comprises a plurality of RF perturbing elements connected to the RF disturbing structure and spaced apart from one another in the direction substantially parallel to the signal path. The perturbing elements are positioned, configured and sized to direct a disturbed portion of the signal away therefrom to reduce field disturbance generated by the disturbed signal portion interacting with an undisturbed portion of the antenna signal.Type: GrantFiled: October 3, 2005Date of Patent: June 26, 2007Inventors: Eric Amyotte, Yan Brand, Virgine Dupessey, Santiago Sierra-Garcia

Patent number: 7138959Abstract: A method for improving the electric isolation of a wide coverage antenna mounted on a structure. The structure defines a peripheral wall and a first end wall and the elongated antenna has a base. The antenna pivotally mounts on the structure about a mounting axis parallel to the structure axis, in a spaced apart relationship relative to the peripheral wall in a direction pointing generally outwardly therefrom with the antenna base and at least part of an antenna body being in a step back relationship relative to the first end wall such that the antenna is at least partially electrically isolated by the structure while being substantially hidden from the first end wall. A second antenna similarly pivotally positioned relative to the peripheral wall can be generally opposed to the first antenna about the structure such that the two antennas are at least partially electrically isolated from one another.Type: GrantFiled: December 30, 2003Date of Patent: November 21, 2006Assignee: EMS Technologies Canada, Ltd.Inventors: Yves Gaudette, Yan Brand

Patent number: 7031696Abstract: A timekeeper equipped with a radio reception device capable of decoding Radio Data System (RDS) information and including a time base, a display for displaying time data supplied by the time base, and an adjustment control for correcting the time data. The radio reception device includes a frequency locking loop for delivering RDS type data derived from a RDS spectrum received on a high-frequency carrier; and a controller which, on the basis of the delivered RDS type data, controls the adjustment control to ensure time setting of the timekeeper. The timekeeper is portable and the radio reception device rejects the spectrum received from a frequency modulated transmitter supplying RDS data, except for the frequency band containing RDS type data.Type: GrantFiled: April 24, 2002Date of Patent: April 18, 2006Assignee: CSEM Centre Suisse d'Electronique et de Microtechnique SA-Recherche et DeveloppementInventors: Johannes F.
