Abstract

La présente invention concerne une structure de ligne de couplage en cascade à cinq sections symétriseur à large bande. La structure de ligne de couplage en cascade à cinq sections comprend une première résistance d'isolation, une seconde résistance d'isolation, une troisième résistance d'isolation, une quatrième résistance d'isolation, une première feuille métallique, une seconde feuille métallique, une troisième feuille métallique, une quatrième feuille métallique, une cinquième feuille métallique, une sixième feuille métallique, une première base et une seconde base. Par la mise en œuvre de la présente invention, une différence de phase entre des ports de sortie adjacents peut être maintenue stable autour de 180°, ce qui permet d'obtenir un bon effet de déphasage entre deux ports de sortie.
