Dans cette invention, une émission par inadvertance d'ondes électromagnétiques est évitée grâce à un agencement selon lequel un tube de guide d'ondes 11 s'étend à l'intérieur d'un substrat diélectrique 13, et selon lequel des éléments métalliques 15 permettant de maintenir une couche métallique de court-circuitage 14 au même potentiel que le tube de guide d'ondes 11 restent le long des deux sections transversales de surface de paroi large du tube de guide d'ondes 11, et sont retirés le long des deux sections transversales de surface de paroi étroite du tube de guide d'ondes 11.
