Title:
DIELECTRIC RESONATOR AND MANUFACTURING METHOD THEREOF
Document Type and Number:
Japanese Patent JP2004282152
Kind Code:
A
Abstract:
To provide a dielectric resonator and a manufacturing method thereof for solving a problem of ununiformized density at molding of ceramic powder and facilitating setting of a shape for deciding the characteristic of the dielectric resonator.
Stepwise recessed parts 11a, 11a', 11b, 11b' comprising faces nearly in parallel with principal faces Sx, Sy of the dielectric resonator are formed at the ridges of the dielectric resonator formed to be nearly a rectangular solid as a whole. The recessed parts are formed by using a punch moved separately from a main body punch and the ceramic powder is powder-molded by using a multi-stage press method.
