Abstract

L’invention concerne un transducteur orthomode et une chaîne de transmission satellite comprenant le transducteur orthomode, pour la transmission d’un premier signal et d’un deuxième signal dans des modes de propagation orthogonaux. Le transducteur comprend : un guide d’onde principal (501, 601) à section carrée ou rectangulaire, deux accès guidés (510, 520) ayant d’une part une extrémité libre par laquelle sont respectivement injectés ou récupérés le premier signal et le deuxième signal, et d’autre part deux bras reliés au guide d’onde principal. Chaque accès guidé comprend une jonction (512, 522, 602) configurée pour relier l’extrémité libre avec les deux bras de l’accès guidé, les deux bras (513, 514, 523, 524, 610, 611) de chaque accès guidé étant reliés au guide d’onde principal en deux emplacements décentrés d’un ou plusieurs côtés du guide d’onde principal de manière symétrique par rapport à un axe de symétrie du guide d’onde principal.
