Title (EN) BANDPASS FILTER
(FR) FILTRE PASSE-BANDE
(JA) 帯域通過フィルタ
Abstract:
(EN) Disclosed is a bandpass filter which includes a rectangular waveguide which is divided into two in the center of the wide face, and a metal plate which is disposed between the rectangular waveguides parallel to the narrow face of the rectangular waveguides, and which forms an approximate ladder shape, having a pair of beams and multiple fins that connect the pair of beams. Within the rectangular waveguide, at least one other waveguide is formed by dividing a waveguide path vertically with respect to the direction parallel to the wide face. Multiple—that is, at least three—resonators are formed in the interior of the rectangular waveguide by the metal plate. Each of the other waveguides connects resonators which jump over at least one of the multiple resonators, forming a pole outside of the pass band.
(FR) L'invention concerne un filtre passe-bande comprenant un guide d'ondes rectangulaire qui est divisé en deux au centre de la face large, et une plaque métallique qui est disposée entre les guides d'ondes rectangulaires parallèlement à la face étroite des guides d'ondes rectangulaires, et qui a une forme approximative d'échelle, possédant une paire de faisceaux et de multiples ailettes qui relient la paire de faisceaux. A l'intérieur du guide d'ondes rectangulaire, au moins un autre guide d'ondes est formé en divisant une trajectoire de guide d'ondes verticalement par rapport à la direction parallèle à la face large. « Multiple » signifie qu'au moins trois résonateurs sont formés à l'intérieur du guide d'ondes rectangulaire par la plaque métallique. Chacun des autres guides d'ondes connecte les résonateurs qui enjambent au moins l'un des résonateurs multiples, formant un pôle à l'extérieur la bande passante.
(JA)  本発明の帯域通過フィルタは、幅広面の中央で2分割された矩形導波管と、矩形導波管の間に矩形導波管の幅狭面と並行に配置され、一対の梁および一対の梁を連結する複数のフィンを有し略梯子状を呈した金属板とを含む。矩形導波管内において、導波路が幅広面に平行な方向に対して上下に分割されることによって少なくとも一つの別の導波管が形成されている。金属板によって矩形導波管内に少なくとも3つの複数の共振器が形成される。別の導波管のそれぞれは、複数の共振器のうち少なくとも一つを飛び越した共振器同士を結合し、通過帯域外に極を形成する。
