    摘要： A dielectric filter comprises a dielectric substrate having an upper surface and a lower surface and first and second side surfaces opposed to each other, a conductor formed on the lower surface of the dielectric substrate; a plurality of λ/2 resonance lines substantially parallel to each other arranged on the upper surface of the dielectric substrate and extending between a first and a second side surface of the substrate, both ends of each of the plurality of resonance lines being open-circuited, each of the plurality of resonance lines comprising a first portion having a first width and a second portion having a second width, the first width being smaller than the second width, thereby forming stepped parts between the first and the second portion; wherein the first portion of a first resonance line is arranged at the second side face, the second portion of the first resonance line is arranged at the first side face, and the second portion of a second resonance line adjacent to the first resonance line is arranged at the second side face.
