Abstract
Filtre pour ondes hyperfréquences. Le filtre comporte une plaque métallique, 2, dans laquelle est découpé un guide à fente, 4; un résonateur en diélectrique, 3, sépare de la plaque métallique 2 par une plaque en diélectrique 1, est coupé électromagnétiquement au guide à fente. Application, en particulier, au domaine des télécommunications.
