Abstract

Une pluralité d'éléments d'antenne (16, 16.1, 16.2, 16.3) sur un substrat diélectrique (12) sont conçues pour lancer et recevoir des ondes électromagnétiques (21) à destination et en provenance d'une direction sensiblement à distance d'un bord convexe (14) ou concave (134) de ce substrat diélectrique (12), au moins deux de ces éléments d'antenne (16, 16.1, 16.2, 16.3) fonctionnant dans différentes directions (58). Les lignes de fente (26) d'antenne à rayonnement longitudinal à fente en cône (16.1) dans une première couche conductrice (18.1) d'un premier côté (20.1) du substrat diélectrique (12) sont couplées à des lignes microbande (34) d'une seconde couche conductrice (18.2) du second côté (20.2) du substrat diélectrique (12). Un réflecteur biconique (64,140) de lentille diélectrique cylindrique conforme (66) ou de lentille plane (68) améliore le diagramme de rayonnement de plan H. Des éléments d'antenne dipôle (16.2) ou des éléments d'antenne Yagi-Uda (16.3) sur la couche conductrice (18.1) du substrat diélectrique (12) peuvent être utilisés en coopération avec des éléments réflechissant associés (96, 98, 108), seuls ou en combinaison avec un réflecteur en coin (100) de plaques conductrices (102) fixé sur les couches conductrices (18.1, 18.2) à proximité des éléments d'antenne à faisceau longitudinal(16, 16.2, 16.3).
