Title:
TUNABLE BAND-PASS FILTER AND METHOD OF CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2019/187761
Kind Code:
A1
Abstract:
A tunable band-pass filter (10) of the present disclosure is provided with: a waveguide (11); a plurality of resonators (121) which are housed in the waveguide (11) and arranged in a longitudinal direction of the waveguide (11); a dielectric plate (13) which extends in the longitudinal direction of the waveguide (11) and is disposed adjacent to the plurality of resonators (121); and a metal pattern (15) for coupling adjustment formed at a position on the dielectric plate (13) corresponding to the middle of the stages of the resonators (121). The dielectric plate (13) has a variable distance from the resonators (121).
