Abstract
A dielectric resonator with an air (or other dielectric) gap axially interrupting the body of the resonator and circuits employing such resonators. Preferably, the resonator body is conical or a stepped cylinder. However, the invention also is workable with a straight-sided cylindrical resonator body.
Claims22
A dielectric resonator comprising a body comprised of dielectric material defining an axial dimension and a radial dimension orthogonal to said axial dimension, said body comprising a first axial body portion, a second axial body portion and a gap between said first and second axial body portions, said gap interrupting the continuity of said dielectric material in said first and second axial body portions along said axial dimension, and an axial through hole, wherein at least one of said first and second axial body portions is conical in shape, and wherein said at least one of said first and second axial body portions that is conical in shape includes a chamfered base.
A dielectric resonator circuit comprising at least first and second diejectric resonators, each resonator comprising a body comprised of dielectric material and defining an axial dimension and a lateral dimension orthogonal to said axial dimension, each said body comprising a first axial body portion, a second axial body portion and a gap between said first and second axial body portions, each said gap interrupting the continuity of dielectric material in said first and second axial body portions along said axial dimension and each said gap comprising a material having a dielectric constant smaller than a dielectric constant of said first body portion and a dielectric constant of said second body portion and said each body including a longitudinal through hole.
