Abstract

L'invention concerne un réflecteur (21) comportant une section coudée (22a) de chaque côté. Les sections coudées (22a) sont constituées de conducteurs de type tige réalisés sous la forme de cadres et comprennent chacun des éléments horizontaux (24) dans les parties supérieure et inférieure et un élément vertical (23) entre les éléments horizontaux (24). Un élément d'antenne (25) est disposé au milieu de la surface avant du réflecteur (21), avec une séparation prescrite (H). L'élément d'antenne (25) est par exemple réalisé au moyen d'un élément d'antenne dipôle et comprend une section d'injection de puissance (27) en son milieu.
