Abstract
A waveguide band-pass filter is disclosed comprising: an input/output gate for a signal; a first inductive discontinuity coupling device; a second inductive discontinuity coupling device and a first waveguide resonator segment coupled to said input/output gate and interposed between the first and the second coupling devices. At least one of the first and the second coupling devices includes at least a resonant coupling structure which extends in the waveguide with a reduced height relative to a height of the first resonator segment and it is shaped for inputting a zero in a transmission frequency response of the filter.
