Abstract

Structure d'antenne à réflecteurs, plus particulièrement à réflecteurs excentrés du type GREGORY dans laquelle les parties concaves des réflecteurs se font face et sont homothétiques par rapport à un point réel situé entre eux. Le réflecteur auxiliaire de plus est illuminé en zone proche par un cornet plus particulièrement un cornet corrugué. Application aux antennes radar et aux télécommunications spatiales.
