Abstract
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 can be obtained with a single dielectric core. In the multimode dielectric resonator apparatus, a dielectric core is configured of a plate-like TM-mode dielectric core portion and a TE-mode dielectric core portion protruding therefrom in the vertical direction, for example in a spherical shape. Five modes, namely a TMx mode, a TMy mode, a TEx mode, a TEy mode, and a TEz mode are used as multiplex modes. In addition, a filter and a duplexer use the multimode dielectric resonator apparatus, and a communication apparatus uses one or both of the filter and the duplexer.
