  • Abstract
    Cylindrical ceramic resonators with TE0n¿ resonant modes are usually used at centimeter frequencies due to their low loss natures. However they have a difficulty in making wide-band band-pass filters in the millimeter-wave region because of the poor coupling factors between the resonators and input/output waveguides. Having this fact in mind, we propose the use of square shaped ceramic resonators. From the theoretical investigations based on the high frequency structure simulator, it is confirmed that the coupling factor of the square shaped ceramic resonator with EH12¿ resonant mode is larger than that of the cylindrical one.
