Abstract

Réseau d’antennes comprenant : -plusieurs antennes élémentaires juxtaposées, chaque antenne élémentaire comportant un guide d’onde dont une face est munie d’un réseau de fentes afin de rayonner à l’extérieur du guide d’ondes au moins partie de l’énergie électromagnétique dans ledit guide d’onde, dans lequel ladite antenne est un composant résultant d’une fabrication additive, la section des dites fentes étant soit non rectangulaire soit rectangulaire avec des côtés non parallèles à la direction longitudinale (z) desdits guides d’onde (20).. Figure à publier avec l’abrégé : Fig. 1.
