Title
(EN) FILTER INCLUDING A FOLDED STRUCTURE RESONATOR FILTER
(FR) FILTRE COMPRENANT UN FILTRE À RÉSONATEUR À STRUCTURE PLIÉE
Abstract
(EN)
A radio frequency filter is disclosed. According to one aspect, the filter includes N stacked planar dielectric layers, N being an integer greater than 1. The filter also includes a first pair of coupled stripline resonators lying in a plane between 5 a first pair of planar dielectric layers. The filter also includes an outermost ground plane on either side of the stack of N stacked planar dielectric layers.
(FR)
L'invention concerne un filtre de radiofréquences. Selon un aspect, le filtre comprend N couches diélectriques planes empilées, N étant un nombre entier supérieur à 1. Le filtre comprend également une première paire de résonateurs à rubans couplés qui se trouvent dans un plan entre une première paire de couches diélectriques planes. Le filtre comprend également un retour de masse le plus à l'extérieur de chaque côté de l'empilement de N couches diélectriques planes empilées.
