Dielectric resonator device, dielectric filter, dielectric duplexer, and communication apparatus |
摘要 |
A dielectric resonator device includes a dielectric plate. An electrode is provided on each of both principal surfaces of the dielectric plate and a plurality of pairs of mutually-opposing electrode openings are formed in the electrodes. Accordingly, the dielectric resonator device functions as a three-stage resonator. Strip lines serving as input/output probes are provided on the upper surface of an input/output substrate. Also, a ground electrode having electrode openings are formed thereon. By providing the dielectric resonator device and an upper substrate on the upper surface of the input/output substrate, a dielectric filter is formed.
