Abstract

L'invention concerne un ensemble antenne comprenant un élément d'antenne (1) placé en amont d'une surface conductrice (2). Le réglage de la caractéristique de rayonnement de l'antenne est basé sur au moins un paramètre de forme de l'entretoise (3) séparant l'élément d'antenne (1) de la surface conductrice (2) et sur au moins un paramètre de forme de la surface conductrice (2).
