| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a novel coaxial-excited waveguide filter, of which the resonator is a new planar resonator called the frequency selective surface (FSS). The new FSSs located at the input and output ports are directly excited by the coaxial line. In the proposed filter, the transition from TEM to TE$_{10}$ mode is done by the resonance of the FSS. Therefore, the backshort length from the coaxial probe to the shorted end can be chosen arbitrarily. Additionally, the coaxial-excited FSS provides one transmission zero at each stopband. As a design example, a three-stage bandpass filter with 4\% bandwidth is demonstrated at $X$ band. The designed filter realizes very compact size of one cavity and has high skirt selectivity with six transmission zeros. The effectiveness of the design results is confirmed by a good agreement between the simulated and experimental results. | |
