Laminated dielectric resonator and laminated dielectric filter |
摘要 |
A space is defined in a portion of an overlapping region where an open end portion of a resonant electrode and an inner-layer ground electrode, of a dielectric layer which is interposed between the resonant electrode and the inner-layer ground electrode. A space is defined in a portion of an overlapping region where the open end portion of the resonant electrode and another inner-layer ground electrode, of a dielectric layer which is interposed between the resonant electrode and the other inner-layer ground electrode. These spaces are filled with respective members having a dielectric constant higher than the dielectric layers.
