Abstract

Système d'antennes directionnelles à polarisation croisée, comportant un réflecteur (11) sensiblement plan et rectangulaire et au moins une cellule rayonnante (10) portée par ledit réflecteur, chaque cellule comportant au moins deux premiers éléments conducteurs (1A, 1B) montés tête-bêche et alimentés par une première source extérieure d'énergie en formant un premier dipôle (1), caractérisé en ce que chaque cellule rayonnante comporte deux deuxièmes éléments conducteurs (2A-2B) montés identiquement aux premiers et alimentés par une deuxième source extérieure d'énergie en formant un deuxième dipôle, et en ce que lesdits éléments conducteurs (1A-1B, 2A, 2B) sont des éléments pliés en forme de Vé et montés orthogonalement les deuxièmes par rapport aux premiers. Application à la téléphonie mobile.
