Abstract
A tunable band-pass filter (10) according to the present disclosure includes: a waveguide (11); a plurality of resonators (121) configured to be accommodated in the waveguide (11) and aligned in a longitudinal direction of the waveguide (11); a dielectric plate (13) configured to extend in the longitudinal direction of the waveguide (11) so to be arranged adjacent to the plurality of resonators (121); and a metal pattern (15) for coupling adjustment formed on the dielectric plate (13) at a position corresponding to an interstage of the resonators (121), in which a distance between the dielectric plate (13) and the resonators (121) is variable.
Claims7
A tunable band-pass filter comprising:
- a waveguide;
- a plurality of resonators configured to be accommodated in the waveguide and aligned in a longitudinal direction of the waveguide;
- a dielectric plate configured to extend in the longitudinal direction of the waveguide so as to be arranged adjacent to the plurality of resonators;
- and
- a metal pattern for coupling adjustment formed on the dielectric plate at a position corresponding to an interstage of the resonators,
- wherein a distance between the dielectric plate and the resonators is variable.
A method for controlling a tunable band-pass filter comprising:
- accommodating a plurality of resonators in a waveguide in an aligned manner in a longitudinal direction of the waveguide;
- arranging a dielectric plate configured to extend in the longitudinal direction of the waveguide so as to be adjacent to the plurality of resonators;
- forming a metal pattern for coupling adjustment on the dielectric plate at a position corresponding to an interstage of the resonators;
- and
- making a distance between the dielectric plate and the resonators variable.
