Abstract

La présente invention a pour objet un réflecteur secondaire d'antenne parabolique comprenant une première extrémité ayant une jonction d'un premier rayon, adaptée pour le couplage à l'extrémité d'un guide d'onde, une seconde extrémité, ayant un second rayon plus grand que le premier rayon, une surface interne convexe réfléchissante placée à la seconde extrémité ayant un axe de révolution, une surface externe de même axe, reliant les deux extrémités, et un corps diélectrique s'étendant entre la première et la seconde extrémité et limité par la surface interne et la surface externe, dans lequel la surface externe a un profil décrit par une équation de la forme : ρ z = α w + ρ 0 - α w 1 - A ⁢ z + L L + A ⁢ sin 2 ⁢ π ⁢ z + L 2 ⁢ L
Figure imga0001
dans laquelle A est une constante numérique non nulle, aw est le premier rayon de la première extrémité du réflecteur secondaire, ρ0 est le deuxième rayon de la deuxième extrémité du réflecteur secondaire, L est la hauteur totale du réflecteur secondaire, z est la hauteur considérée du réflecteur secondaire, et ρ(z) est le rayon d'une section placée à la hauteur z du réflecteur secondaire.
Selon une variante, la surface externe du réflecteur secondaire comporte une pluralité de reliefs annulaires entourant le corps diélectrique, et la ligne reliant les surfaces externes des reliefs est décrite par cette équation.
