Abstract:
A coaxial resonator comprising:a dielectric block having at least four side surfaces, each of said at least four side surfaces having a respective outer peripheral surface and said dielectric block having a inner peripheral surface, each said respective outer peripheral surface and said inner peripheral surface being parallel to each other along a common axis, and said dielectric block further having first and second end faces crossing said axis;first and second layers of a conductor coating respectively disposed on said corresponding outer peripheral surface and said inner peripheral surface;a third conductor layer disposed on said second end face for short-circuiting said first and second conductor layers; anda conductor for induction, having a portion parallel to the second conductor layer, disposed on at least one of said outer peripheral surfaces in a position in proximity to said second end face, and is brought into direct electrical contact with only said third conductor layer and is provided independently of said first conductor layer.
