Abstract―The dielectric combline resonator combines the merits of the metallic combline and dielectric loaded resonator. By replacing the inner conductor of the conventional combline resonator by a high r dielectric rod, higher unloaded Q can be expected. Resonant frequency, unloaded Q, and coupling coefcient of the resonator are obtained by a rigorous mode-matching method. An eight-pole elliptic-function dielectric combline resonator lter was designed and tested. Measured frequency responses verify the theory. Index Terms― Combline resonator, dielectr
