Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a high-performance waveguide filter constructed by novel resonant metallic windows, which have a resonant characteristic with two attenuation poles on each side of a passband. We have already proposed waveguide filters using frequency selective surfaces (FSSs), but they have the problem that both dielectric and conductor losses bring some insertion losses in a passband. In this paper, introducing a new resonant window without a dielectric support improves the passband characteristic. The filter with the proposed windows has high skirt selectivity by utilizing the anti-resonances, and also realizes a drastic size reduction by controlling the resonant curve of each window. As design examples, we show two waveguide filters at X band. The validity of the waveguide filters is proved by the comparison of the frequency characteristics between the calculated and the measured results.
