Abstract

L'invention concerne un cornet rayonnant une onde radioélectrique, issue d'un guide d'onde d'entrée, comprenant une grille disposée au niveau de l'ouverture du cornet. Elle s'applique notamment au domaine des antennes à réflecteur. Le guide d'onde comporte un tronçon (12) en forme de cornet, une entrée (13), une ouverture (14), et une grille (21) disposée au voisinage de l'ouverture (14). Il permet la propagation d'une onde électromagnétique à polarisation linéaire entre l'entrée (13) et l'ouverture (14) selon un premier axe (z). La grille (21) comporte un ensemble de lames (211-213) de manière à former un filtre de polarisation linéaire pour toute onde électromagnétique dont le champ électrique n'est pas polarisé selon un deuxième axe (y) orthogonal au premier axe (z). Selon l'invention, la grille (21) du guide d'onde (20) comprend des corrugations (22) de manière à renforcer le filtrage de toute onde électromagnétique dont le champ électrique n'est pas polarisé selon le deuxième axe (y).
