Abstract(in Japanese) (See Japanese page)
Abstract(in English) A new method of constructing evanescent-mode bandpass filter with attenuation poles is proposed.It is very basic for evanescent- mode waveguide bandpass filters that the decreased insertion loss remains inevitably in the off-passband higher than the passband center frequency.To improve such a feature,we propose here a new idea,the modeselective negative coupling,for implementing multiple attenuation poles in the far-out-of-passband for evanescent-mode waveguide filters.Experiments prove the effectiveness of our new idea.
