Claims

[Claims for Utility Model Registration] (1) The main surface of the dielectric block has a U-shaped cross section.
1. A dielectric resonator characterized in that a character-shaped groove is formed, an inner conductor film is provided on the inner surface of the groove, and an outer conductor film is provided on the outer surface except for the open end surface where one end of the groove is located. (2) The dielectric resonator according to claim 1, wherein the inner conductor film and the outer conductor film are separated by a band-shaped portion on the main surface or the inner surface of the groove where no conductor film is present. (3) The dielectric block has a convex portion protruding from the open end surface, and a connecting conductor film connected to the inner conductor film is formed on an extended surface and a tip end surface of the convex portion continuous with the inner surface of the groove. The dielectric resonator according to claim 1. (4) The main surface of the dielectric block has a U-shaped cross section.
A dielectric resonator comprising a letter-shaped groove, an inner conductor film provided on the inner surface of the groove, and an outer conductor film provided on the outer surface excluding the open end surface where one end of the groove is located, and at least a portion facing the groove. a printed wiring board having a grounding pattern that connects to the outer conductor film while avoiding the interference, the main surface of the dielectric block is brought into contact with the printed wiring board, and the outer conductor film is connected and fixed to the grounding pattern. A dielectric resonator mounting structure characterized by: (5) A convex portion protruding from the open end surface is formed on the dielectric block, and a connecting conductor film connected to the inner conductor film is provided on an extended surface and a tip end surface of the convex portion continuous with the inner surface of the groove, and 5.
