Title
(DE) PHASENGESTEUERTE GRUPPENANTENNE MIT UNABHÄNGIG STEUERBAREN STRAHLEN
(EN) PHASED ARRAY WITH INDEPENDENTLY STEERABLE BEAMS
(FR) RÉSEAU À COMMANDE DE PHASE À FAISCEAUX ORIENTABLES INDÉPENDAMMENT
Abstract
(EN) Various antenna systems are presented that have independently steerable receive and transmit beams. The antenna system may include multiple antenna element systems. Each antenna element system may include multiple phase shifters that alter the phase of received signals and signals to be transmitted. Directions of a first transmit beam, a second transmit beam, a first receive beam, and a second receive beam may be steered independently using the phase shifters. Each antenna element system may include a polarization system.
(FR) Divers systèmes d'antenne sont présentés qui comprennent des faisceaux de réception et d'émission orientables indépendamment. Le système d'antenne peut comprendre de multiples systèmes d'éléments d'antenne. Chaque système d'éléments d'antenne peut comprendre de multiples déphaseurs qui modifient la phase des signaux reçus et des signaux à transmettre. Les directions d'un premier faisceau d'émission, d'un second faisceau d'émission, d'un premier faisceau de réception et d'un second faisceau de réception peuvent être orientées indépendamment à l'aide des déphaseurs. Chaque système d'élément d'antenne peut comprendre un système de polarisation.
