ABSTRACT:
Structure for use in forming a resonant circuit eliminates a support block for the installation of a dielectric resonator, by providing a satisfactory way to directly install the dielectric resonator on a microwave circuit board having a microstrip line. The dielectric resonator is directly fixed on the microwave circuit board in such a manner that mutually opposing planar surfaces thereof do not face one planar surface of the microwave circuit board, and an axial line passing normally through these planar surfaces intersects a normal plane projected from the microstrip line. As a result, production costs can be reduced and simplified work processes can be used to fabricate the structure. Further, an electrode film may be formed on a flat part of the outer periphery of the dielectric resonator, and such a dielectric resonator is fixed on the microwave circuit board with the flat part on which said electrode film is formed, facing upwards. As a result, a metallic case which is to cover the microwave circuit board can be brought close to the dielectric resonator, thereby achieving a compact overall structure.
