摘要： A compact dielectric resonator apparatus is comprised of a dielectric block having a plurality of mutually parallel throughholes formed therethrough with inner surfaces covered with a conductive film so as to provide coaxial resonators. The degree of coupling between a mutually adjacent pair of such dielectric resonators can be adjusted by forming grooves, a bottomed hole or a slit or burying a conductive plate therebetween in the dielectric block, and varying physical characteristics of such grooves, bottomed hole, slit and/or conductive plate, without changing the separations between the throughholes or the external dimensions of the dielectric block.

摘要： A dielectric filter is provided which permits one to obtain desired external coupling easily without lowering Qo of resonators. The filter comprises a dielectric block having an open end surface and a shorted end surface and provided with resonator holes. Excitation holes are formed in the block outside the resonator holes, respectively. Input/output electrodes are formed on the open end-surface. The electrodes are electrically connected with conductors formed inside the excitation holes but isolated from an outer conductor. The conductors inside the excitation holes are electrically connected with the outer conductor on the shorted end surface. The excitation holes are electromagnetically coupled to the respective adjacent resonator holes, thus providing external coupling.

摘要： Grooves are formed on the connection faces of two dielectric base plates in a dielectric resonator. Internal conductors are provided on the inside faces. Coupling electrodes are formed on another dielectric base plate. These three dielectric base plates are connected so that the coupling electrode effects a capacity connection between the internal conductors. This arrangement permits an earth electrode (e.g., an external conductor) to be formed on almost the full exterior of the dielectric resonator, thereby preventing the reduction of the Qo of the resonator and electromagnetic field leakage.
