Abstract
L'invention concerne les antennes directionnelles. Une antenne directionnelle comprend essentiellement un réflecteur parabolique principal 10, un sous-réflecteur parabolique 12, et réseau d'excitation 14. Cette configuration permet de tolérer des imperfections relativement importantes de la surface du réflecteur principal 10. On peut en effet corriger les distorsions de champs qui résultent de telles imperfections, en ajustant la distribution de phase des éléments du réseau 14. Application aux télécommunications par satellite.
