Abstract

L'antenne en plaque est constituée par deux couronnes circulaires tangentes C1, 2 avec une fente 9 étroite orientée suivant l'axe 10 joignant les centres des couronnes et allant du bord interne d'une couronne jusqu'au bord interne de l'autre couronne. La zone de tangences a une certaine largeur dans la direction perpendiculaire à l'axe. Un bord de la fente est excité au voisinage immédiat du centre de symétrie de l'antenne tandis que le point milieu d'au moins une couronne situé sur ledit axe de l'autre côté du centre est à la masse. Les antennes peuvent être assemblées en réseau. Elles peuvent être réalisées en circuits imprimés double face. Utilisables pour réaliser des antennes directes de petites dimensions.
