Abstract

L'invention concerne un filtre passe-haut. L'invention concerne, selon un mode de réalisation, un filtre passe-haut qui comprend : une plaque de base constituée d'un matériau conducteur; et un ou plusieurs pôles résonants qui s'étendent en parallèle avec la plaque de base au niveau d'une extrémité avant de la plaque de base, sont formés d'un seul tenant avec la plaque de base, sont pliés par rapport à la plaque de base, et sont configurés pour former une résonance dans une bande de fréquence dans laquelle le filtre passe-haut est utilisé.
