Abstract
L'invention concerne les antennes hyperfréquences. Le dispositif d'excitation 10 d'une antenne parabolique Il, de type disque, comprend notamment deux éléments de modification de diagramme 30, 31, qui se présentent sous la forme de bandes métalliques fixées sur un câble coaxial rigide 13 qui porte un élément rayonnant primaire 15. Les éléments 30, 31 réduisent la largeur du faisceau à demi-puissance, tout en augmentant le gain de l'antenne. Application aux antennes de télécommunications.
