Multimode dielectric resonator apparatus, filter, duplexer and communication apparatus |
摘要 |
A multimode dielectric resonator apparatus is configured such that a TM mode and a TE mode are transformed into multiplex modes, coupling between individual resonant modes can be easily made, and a large number of sequentially coupled stages for a single dielectric core can be obtained. A dielectric core is configured of a plate-like TM-mode dielectric core portion and a TE-mode dielectric core portion protruding therefrom asymmetrically in the upper and lower directions. By this asymmetry of the TE-mode dielectric core portion with respect to the TM-mode dielectric core portion, for example, a TMx mode and a TEz mode may be coupled together, and concurrently, a TMy mode and a TEz mode may be coupled together.
