(FR) DISPOSITIF DE TELECOMMUNICATION A RESEAUX A BALAYAGE ELECTRONIQUE CONFORME ET TERMINAL DE TELECOMMUNICATION ASSOCIE
Abstract
(EN)
The invention concerns a telecommunication device with electronic scanning arrays shaped along a first surface with symmetry of revolution, comprising: a first array of first radiating sources (5) arranged along said surface to operate about a first centre frequency. The invention is characterised in that the device further comprises: a second array of radiating sources arranged along a second surface with symmetry of revolution to operate about a second centre frequency, the first and second sources being respectively arranged such that a first source, respectively a second source, is not opposite a second source, respectively a first source, along a cross cut of the first and second surfaces pointing on the first source, respectively the second source. The invention also concerns a telecommunication terminal in a constellation system by satellites and a wireless communication terminal for communicating with household equipment comprising said inventive device.

L'invention concerne un dispositif de télécommunications à réseaux à balayage électronique conformé selon une première surface à symétrie de révolution, comprenant: un premier réseau de premières sources rayonnantes (5) agencé selon ladite première surface pour fonctionner autour d'une première fréquence centrale. Selon l'invention, le dispositif comprend en outre: un second réseau de secondes sources rayonnantes agencé selon une seconde surface à symétrie de révolution adjacente à ladite première surface pour fonctionner autour d'une seconde fréquence centrale, les premières et secondes sources étant respectivement disposées de sorte qu'une première source, respectivement une seconde source, n'est pas en regard d'une seconde source, respectivement une première source, selon une coupe normale des première et seconde surfaces pointant sur la première source, respectivement la seconde source. L'invention concerne également un terminal de télécommunications dans un système de constellation par satellites et un terminal de communication sans fil pour communiquer avec des équipements domestiques comprenant un dispositif selon l'invention.
