Abstract :
Cylindrical ceramic resonators with TE/sub 0n/spl delta// 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 and experimental investigations, it is confirmed that the coupling factor of the square shaped ceramic resonator with EH/sub 12/spl delta// resonant mode is larger than that of the cylindrical one.
