Abstract
(EN)
The present invention provides a filter device that comprises a post wall waveguide, and for which the pass band is variable. This filter device (1) comprises a post wall waveguide (filter body 1M) that functions as a plurality of resonators (10-50); cavities (tubes 551-555) that are joined with each resonator (10-50) with apertures (AP1-AP5) formed on a wide wall (conductor layer 2) interposed therebetween; rods (61-65) inserted in the cavities (tubes 551-555); and a rod control mechanism (piezoelectric element 6P) that controls the position of the rods (61-65).

La présente invention concerne un dispositif de filtrage qui comprend un guide d'ondes de post-paroi, et pour lequel la bande passante est variable. Ce dispositif de filtre (1) comprend un guide d'ondes de post-paroi (corps de filtre 1M) qui fonctionne comme une pluralité de résonateurs (10-50) ; des cavités (tubes 551-555) qui sont reliées à chaque résonateur (10-50) avec des ouvertures (AP1-AP5) formées sur une paroi large (couche conductrice 2) interposée entre celles-ci ; des tiges (61-65) insérées dans les cavités (tubes 551-555) ; et un mécanisme de commande de tige (élément piézoélectrique 6P) qui commande la position des tiges (61-65).
