<P>PROBLEM TO BE SOLVED: To stably make satisfactory the alignment of a dielectric and a high frequency transmission line even in mass-production. <P>SOLUTION: In a high frequency circuit having substrate having the high frequency transmission line and a dielectric resonator provided on the substrate to be electromagnetically coupled to the high frequency transmission line, a hole or hollow portion is formed on one part of the substrate and the dielectric resonator is embedded in this hole or the hollow portion. Besides, for similar purposes, the high frequency circuit having the dielectric resonator is produced by a process for forming the high frequency transmission line on the substrate, a process for forming the hole or the hollow portion partially on the substrate and a process for embedding the dielectric resonator in the hole formed on the surface of the substrate. <P>COPYRIGHT: (C)2003,JPO |
