As características básicas de um ressonador de guia de onda coplanar de extremidade curta (CPW) com boa propriedade de supressão espúria são estudadas. O ressonador é carregado com tubos abertos em sua posição intermediária e forma uma estrutura totalmente plana. O comprimento do ressonador é reduzido quase pela metade e a primeira ressonância espúria sobe para mais de 3 vezes a frequência ressonante fundamental sem degradação da energia descarregada. Q(Q0). A origem e a propriedade da resposta espúria são minuciosamente investigadas para mostrar a vantagem e o limite desta configuração. O externo Q(Qe) e a frequência ressonante fundamental do ressonador também são esclarecidas teórica e experimentalmente. Usando esses resultados, um filtro passa-banda (BPF) é projetado com base na aproximação de banda estreita e suas características de transmissão são examinadas teórica e experimentalmente. As características de supressão espúrias foram realizadas pelo presente filtro de acordo com a expectativa.

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.
