Abstract
Une antenne en cornet elliptique relativement abordable, facile à installer et esthétiquement agréable pour la diffusion vidéo numérique par satellite (DVB-S), conçue comme une partie d~un système d~antenne à réflecteur pour recevoir les signaux de vidéo numérique par polarisation circulaire. Ce type d~antenne peut être instaurée avec un simple cornet d~alimentation, avec un cornet d~alimentation multiple qui peut être arrangé séparément ou en un ou plusieurs bloc entier de cornets d~alimentation (304, 306). Ces antennes peuvent être conçues pour réaliser une performance acceptable de polarisation circulaire comparée aux bandes de fréquences larges et multiples, par l~utilisation de phases et sections différentielles inclinées à l~opposé.
