Les caractéristiques de base d'un résonateur à guide d'ondes coplanaire à extrémités courtes (CPW) présentant de bonnes propriétés de suppression des parasites sont étudiées. Le résonateur est chargé de cuves ouvertes en position médiane et constitue une structure entièrement plane. La longueur du résonateur est raccourcie presque de moitié et la première résonance parasite monte jusqu'à plus de 3 fois la fréquence de résonance fondamentale sans dégradation du son à vide. Q(Q0). L'origine et la propriété des réponses parasites sont étudiées de manière approfondie pour montrer l'avantage et les limites de cette configuration. L'extérieur Q(Qe) et la fréquence de résonance fondamentale du résonateur sont également clarifiées théoriquement et expérimentalement. À l'aide de ces résultats, un filtre passe-bande (BPF) est conçu sur la base d'une approximation à bande étroite et ses caractéristiques de transmission sont examinées théoriquement et expérimentalement. Les caractéristiques de suppression parasite ont été réalisées par le présent filtre conformément aux attentes.

Abstract: Basic characteristics of a short-ended coplanar waveguide (CPW) resonator of good spurious suppression property is studied. The resonator is loaded with open tubs at its middle position and makes a fully planar structure. The length of the resonator is shortened almost by half and the first spurious resonance goes up to more than 3 times of the fundamental resonant frequency without degradation of unloaded Q(Q0). The origin and property of spurious response is thoroughly investigated to show the advantage and the limit of this configuration. The external Q(Qe) and fundamental resonant frequency of the resonator are also clarified theoretically and experimentally. Using those result, a bandpass filter (BPF) is designed on the basis of the narrow band approximation is realized and its transmission characteristics are examined theoretically and experimentally. The spurious suppression characteristics have been realized by the present filter in accordance with the expectation.
