Abstract
(EN) An improved control system for controlling radiation direction of an antenna beam of an antenna is disclosed. The radiation direction is adjustable by an actuating device influencing phase shifting means based on an actuating signal. The system includes filtering means, arranged for filtering out a control signal and being connected, in use, to a feeder cable arranged for carrying RF signals and control signals. The system further includes an external control unit including detecting means, arranged for detecting the filtered out control signal, and control means, arranged for producing the actuating signal based on the detected control signal. The filtering means is directly connected to the external control unit so as to provide the filtered out control signal directly to the external control unit.
(FR) La présente invention concerne un système de commande amélioré destiné à commander la direction de radiation d'un faisceau d'antennes d'une antenne. La direction de radiation peut être ajustée par un dispositif d'actionnement influençant les moyens de déphasage en fonction d'un signal d'actionnement. Le système comprend des moyens de filtrage, disposés pour filtrer un signal de commande et étant connecté, en utilisation, à un câble d'alimentation disposé pour transporter des signaux RF et des signaux de commande. Le système comprend également une unité de commande externe, incluant des moyens de détection, disposée pour détecter le signal de commande filtré, et des moyens de commande destinés à produire le signal d'actionnement en fonction du signal de commande détecté. Les moyens de filtrage sont directement connectés à l'unité de commande externe de manière à fournir le signal de commande filtré à l'unité de commande externe.
