Abstract

Antenne La présente invention concerne une antenne (10) comportant : un élément rayonnant primaire (11) configuré pour rayonner des ondes radio ; et un réflecteur parabolique (12) configuré pour réfléchir les ondes radio rayonnées par l’élément rayonnant primaire (11) et qui a un diamètre d’ouverture réduit pour être inférieur ou égal à un diamètre d’ouverture avec lequel aucun point nul n’est généré dans un diagramme d’antenne dans une demi-sphère où les ondes radio sont réfléchies et rayonnées. Figure pour l’abrégé : Fig. 2
