Abstract

La présente invention concerne une structure de ligne de couplage en cascade à sections multiples. La structure de ligne de couplage en cascade à sections multiples est constituée d'une structure en forme de tour, et comprend un corps de tour formé en superposant de multiples sections de feuilles métalliques et une base de tour constituée de deux feuilles métalliques de base sur la gauche et la droite du corps de tour. A l'exception de la feuille métallique de section supérieure au sommet du corps de tour, les autres feuilles métalliques formant le corps de tour sont séparées intérieurement d'un espace. Une résistance de barrière est disposée dans chaque espace. La mise en œuvre de la présente invention permet de libérer des signaux dans une carte de circuit imprimé par étape, ce qui permet d'améliorer la stabilité de transmission de signal dans la conception de carte de circuit imprimé.
