Abstract[English]
A waveguide filter is provided. The waveguide filter comprises at least one waveguide resonator that resonates radio waves in a TE mode. The waveguide resonator is provided with a coupling window to which an input waveguide line or an output waveguide line is connected. The coupling window has two long sides extending in a longitudinal direction and facing in a short-side direction, wherein a middle part of at least one of two long sides is farther from another long side than both side parts. Selection Diagram: Figure 2[French]
La présente invention concerne un filtre à guide d'ondes. Le filtre à guide d'ondes comprend au moins un résonateur à guide d'ondes qui fait résonner les ondes radio en mode TE. Le résonateur à guide d'ondes est pourvu d'une fenêtre de couplage à laquelle est connectée une ligne de guide d'ondes d'entrée ou une ligne de guide d'ondes de sortie. La fenêtre de couplage a deux côtés longs s'étendant dans une direction longitudinale et faisant face à une direction de côté court, une partie centrale d'au moins un des deux côtés longs étant plus éloignée d'un autre côté long que les deux parties latérales.
