Abstract
REFLECTEUR PERMETTANT D'AMELIORER LES PERFORMANCES D'UNE ANTENNE. LA FACE REFLECHISSANTE D'UN REFLECTEUR AUXILIAIRE 1 D'UNE ANTENNE 1, 2, 3 COMPORTE DES RAINURES (CORRUGATIONS DANS LA LITTERATURE ANGLO-SAXONNE). CES RAINURES SONT DES RAINURES CONCENTRIQUES, DETERMINEES DE MANIERE QUE LE RAYONNEMENT A L'INFINI DE L'ANTENNE SOIT EN MODE HE; ELLES PERMETTENT DE REDUIRE LA POLARISATION CROISEE DANS L'ONDE EMISE PAR L'ANTENNE. APPLICATION AUX ANTENNES A REFLECTEURS AUXILIAIRES, UTILISEES EN HYPERFREQUENCE.
