Abstract
A band-pass filter having a body, a rectangular waveguide, and a dielectric insert, the dielectric insert has a dielectric plate and a high temperature superconductive film in line with a plurality of rectangular windows of the same height. The waveguide has a×b cross-section, a being length of the long side walls and b the length of the short side walls. Each long side wall has a fixing groove at the central portion and a rectangular recess in the fixing groove. The dielectric plate has two ends in the fixing grooves and is symmetric with a perpendicular bisecting plane of the long side wall. The rectangular recess is symmetric to the perpendicular bisecting plane and has the same length as that of the waveguide, with its width w satisfying t<w<a/2, and depth d satisfying d<λ/4, t being total thickness of the dielectric plate and the high temperature superconductive film, and λ the wavelength of the central frequency of the pass-band of the band-pass filter.
