  • Rectangular band-pass filter having recesses of less than one-quarter wavelength depth formed therein for fitting a dielectric insert with a superconductive film within the recesses
    Patent number: 9537195
    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<?/4, t being total thickness of the dielectric plate and the high temperature superconductive film, and ? the wavelength of the central frequency of the pass-band of the band-pass filter.

  • BAND-PASS FILTER
    Publication number: 20150188208
    Abstract: Band-pass filter having a body comprising a rectangular waveguide and a dielectric insert comprising a dielectric plate and a high temperature superconductive film in line with a number of rectangular windows of the same height. The waveguide has a×b cross-section, a being length of the wide wall and b the length of the narrow wall. Each wide 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 wide wall. The rectangular recess is symmetric to the perpendicular bisecting plane and has same length as the waveguide, with its width w satisfies t<w<a/2, and depth d satisfies d<?/4, t being total thickness of the dielectric plate and the high temperature superconductive film, and ? the wavelength of the central frequency of the pass-band of the band-pass filter.
