CERAMIC BODY FOR DIELECTRIC RESONATOR AND MANUFACTURING METHOD THEREOF, DIELECTRIC RESONATOR EMPLOYING THE SAME, AND ANTENNA DUPLEXER

摘要

PROBLEM TO BE SOLVED: To provide a ceramic body for a dielectric resonator with a high no-load Q wherein the dielectric resonator and a support base are strongly tightened and fixed and to provide a manufacturing method thereof and the dielectric.

SOLUTION: The dielectric resonator use ceramic body comprises: the columnar or cylindrical dielectric resonator made of a dielectric ceramic material; and the support base 14 made of a ceramic material for supporting an end of the dielectric resonator 12. In the dielectric resonator use ceramic body, the end of the dielectric resonator 12 and the end of the support base 14 are tightened and fixed by fitting and the dielectric ceramic material of the dielectric resonator 12 and the ceramic material of the support base 14 are diffused in borders 30 between the dielectric 12 and the support base 14.
