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.
