Abstract

Une pluralité d'éléments d'alimentation d'antenne à rayonnement longitudinal (14, 14.1) disposés le long d'un pourtour (30) sur un substrat diélectrique (16) coopérant avec un réseau de lentilles distinctes (100). Une onde électromagnétique (20) lancée par un élément d'alimentation d'antenne (14, 14.1) est reçue par un premier ensemble d'antennes à plaque (102.1) sur un premier coté (104) du réseau (100), et les signaux reçus associés sont propagés par l'intermédiaire d'éléments de délais associés (108) vers un second ensemble correspondant d'antennes à plaque (102.2) sur le côté opposé (106) du réseau (100) à partir duquel les signaux reçus associés sont radiés à nouveau, les délais correspondants des éléments de délais associés (108) dépendent de l'emplacement de manière à émuler une lentille électromagnétique diélectrique (12) formant ainsi un faisceau associé d'énergie électromagnétique (20). Un signal appliqué sur un support d'alimentation d'entreprise (54) est commuté vers les éléments d'alimentation d'antenne (14, 14.1) par un réseau de commutation (48), différents éléments d'alimentation d'antenne (14, 14.1) générant différents faisceaux (20) d'énergie électromagnétique dans différentes directions (42).
