Abstract
L'ANTENNE LENTILLE DE TYPE LUNEBERG EST FORMEE PAR UN DISQUE 10 EN MATERIAU DIELECTRIQUE DONT L'INDICE DE REFRACTION (OU CONSTANTE DIELECTRIQUE) VARIE SUIVANT LE RAYON DU DISQUE, CE DERNIER ETANT ENTOURE DE PART ET D'AUTRE DE FACES METALLIQUES CONDUCTRICES 11, 12. DE PREFERENCE, L'ANTENNE EST CONCUE POUR LA TRANSMISSION D'UNE ONDE POLARISEE SOUS UN ANGLE DE 45 PAR RAPPORT AU PLAN DE LA LENTILLE. LES HAUTEURS D'AIR ET DE DIELECTRIQUE SONT TELLES QU'UNE ONDE A COMPOSANTE DE CHAMP ELECTRIQUE PARALLELE AU PLAN DE LA LENTILLE A MEME DEPHASAGE QU'UNE ONDE A COMPOSANTE DE CHAMP ELECTRIQUE PERPENDICULAIRE AU PLAN DE LA LENTILLE. APPLICATION: RECEPTION DE MICRO-ONDES.
