Abstract (en)
[origin: US4746883A] The microwave bandpass filter in the form of a cutoff frequency waveguide (1) or evanescent mode guide, being besides tunable within a range of frequencies and having at least one terminal (21, 22) of the coaxial type, has terminals each equipped with a crank-shaped coupling antenna (15) operable to be rotated about its longitudinal axis for filter tuning purposes.
