ABSTRACT:
A waveguide filter comprises waveguides with length corresponding to the center frequency of a band pass filter, and shunt plates. Each shunt inductor plate has sufficient size to cover an opening of the wave guide and includes an induction window smaller than the opening, and each opening is opposed to each induction window. The waveguides and the shunt inductor plates are alternately arranged in close contact state, and the center frequency of the filter scarcely deviates.
