Although TE_<0nδ> mode ceramic resonators are usually used at centimeter frequencies, they have difficulty in making wide-band band-pass filters in the millimeter-wave region due to the weak coupling factors between TE_<0nδ> mode resonators and input/output waveguides. In order to overcome such difficulty, a band-widening technique of the ceramic resonator loaded band-pass filter has been proposed. The EH_<nmδ> modes were regarded as spurious modes so far, but it is clear that the coupling factors are larger than those of the TE_<0nδ> modes from the results of experimental considerations in this paper. By using the EH_<11δ> mode ceramic resonators, 5-pole, 1dB Chebyshev ripple NRD guide band-pass filter has been fabricated for the applications to broad-band millimeter-wave communication systems at 60GHz. The filter has great advantages such as the wide passband beyond 2GHz and low excess insertion loss of less than 0.3dB.
