摘要： A method for easily adjusting the frequency of an attenuation pole in a dual-mode band pass filter which is very compact and greatly increases coupling strength while maintaining a great deal of freedom of design. The dual-mode band pass filter includes a metal film partially disposed on a main surface of a dielectric substrate or disposed inside of the dielectric resonator so as to define a resonator. An opening is formed in the metal film to couple two resonance modes. Input/output coupling circuits are coupled to the metal film. At least one of coupling portions of the input/output coupling circuits or input/output portions thereof are moved in a direction along a perimeter of the metal film.

摘要： A method of producing a band-pass filter includes selecting the shape of a metallic film and the connection points of input-output coupling circuits such that first and second resonance modes are generated in a metallic film provided on a dielectric substrate. At least a portion of the resonance current or the resonance electric field in at least one of the resonance modes is made discontinuous such that the first and second resonance modes are coupled.
