Title (EN) NETWORK ANTENNA WITH SHAPED REFLECTOR(S) HIGHLY RECONFIGURABLE IN ORBIT
(FR) ANTENNE RESEAU A REFLECTEUR(S) CONFORME(S), A FORTE RECONFIGURABILITE EN ORBITE
Abstract:
(EN) The invention concerns a network antenna with reflector(s) (AR) comprising i) a network (RS) of at least two sources (S1-S5), including a central source (S1), arranged and positioned so as to transmit and/or receive beams (F1-F5) in selected directions; ii) beam-forming means for controlling the amplitude and the phase of each of the sources using amplitude/phase laws applied upon their inputs and for providing an appropriate amplifying level, so that each source (S1-S5) transmits a selected radiated pattern (forming a beam and including a main lobe) designed to cover a selected zone (Z1-Z5), and iii) at least one reflector (RC) provided with a surface (SU) capable of reflecting the beams output by the sources and/or transmitted thereto, and shaped in three dimensions so as to reflect the beam output by each source (S1-S5) by spreading its energy so that it covers the selected associated zone, and the main lobe of the radiation pattern associated with the central source (S1) defines a primary coverage (CP) including in its entirety each active coverage zone (ZC1, ZC2) of the antenna, of selected shape and dimensions, and the main lobe of the radiation pattern associated with each non-central source (S2-S5) at least party overlaps the primary coverage (CP).
(FR) Une antenne réseau à réflecteur(s) (AR) comprend i) un réseau (RS) d'au moins deux sources (S1-S5), dont une source centrale (S1), agencées et positionnées de manière à émettre et/ou recevoir des faisceaux (F1-F5) dans des directions choisies, ii) des moyens de formation de faisceaux chargés de contrôler l'amplitude et la phase de chacune des sources au moyen de lois d'amplitude/phase appliquées sur leurs accès et d'assurer un niveau d'amplification approprié, afin que chaque source (S1-S5) émette un diagramme de rayonnement choisi (constituant un faisceau et comprenant un lobe principal) destiné à couvrir une zone choisie (Z1-Z5), et iii) au moins un réflecteur (RC) muni d'une surface (SU) propre à réfléchir les faisceaux délivrés par les sources et/ou destinés à celles-ci et conformée de façon tridimensionnelle de manière à réfléchir le faisceau délivré par chaque source (S1-S5) en étalant son énergie de sorte qu'il couvre la zone associée choisie, que le lobe principal du diagramme de rayonnement associé à la source centrale (S1) définisse une couverture primaire (CP) englobant intégralement chaque zone de couverture active (ZC1, ZC2) de l'antenne (AR), de forme et dimensions choisies, et que le lobe principal du diagramme de rayonnement associé à chaque source non centrale (S2-S5) recouvre au moins partiellement la couverture primaire (CP).
