Abstract

Antenne du type discône omnidirectionnelle en gisement et à diagramme de directivité réglable en site. Interposition du côté du sommet de chaque cône d'un disque diélectrique d'épaisseur déterminée, parallèle à la base du cône considère ; ces deux disques créent dans la partie centrale de l'antenne considérée, des conditions de propagation de l'énergie différente de celle existant en dehors des disques, le résultat étant dans l'ouverture rayonnante de l'antenne, une amélioration de la loi de phase. Application aux radars et aux télécommunications.
