A waveguide band-pass filter (100) is disclosed comprising: an input/output gate (3) for a signal; a first inductive discontinuity coupling device (4); a second inductive discontinuity coupling device (6) and a first waveguide resonator segment (5) coupled to said input/output gate (3) and interposed between the first and the second coupling devices. At least one of the first and the second coupling devices (4, 6) 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.

Abstract
A waveguide band-pass filter (100) is disclosed comprising: an input/output gate (3) for a signal; a first inductive discontinuity coupling device (4); a second inductive discontinuity coupling device (6) and a first waveguide resonator segment (5) coupled to said input/output gate (3) and interposed between the first and the second coupling devices. At least one of the first and the second coupling devices (4, 6) 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
