Title:
DIELECTRIC COAXIAL RESONATOR AND CONDUCTIVE FILM FORMING METHOD FOR SAME
Document Type and Number:
Japanese Patent JP3498186
Kind Code:
B2
Abstract:

PURPOSE: To easily produce the dielectric coaxial resonator and to simplify a utilization by standardizing the external shape.
CONSTITUTION: An electrode 4 is formed on an inside peripheral face 2A of a through hole 3, outside peripheral faces 2B parallel with the axis, and one end face 2C of a prismatic dielectric 2, which has a square section and has the circular through hole 3 formed on the axis and is made of ceramics or the like, to constitute a dielectric coaxial resonator 1. Dimensions L1 in the axial direction of the dielectric 2 are made longer than dimensions L2 in the axial direction based on the wavelength of the resonance frequency of the electrode 4, and the dimensions L2 in the axial direction of the electrode 4 are adjusted to easily constitute the dielectric coaxial resonator having an arbitrary resonance frequency.
