Abstract:
1. A resonator comprising: a multilayer substrate including a plurality of alternately stacked dielectric layers and conductor layers, the multilayer substrate having conductor opening portions arranged in a stacking direction of the dielectric layers and the conductor layers, the conductor opening portions forming at least two inductive regions, and at least one portion where the conductor layers face each other in the stacking direction with the corresponding dielectric layers interposed therebetween, the at least one portion serving as a capacitive region and interconnecting the at least two inductive regions, wherein at least one resonator element is provided for each of the at least two inductive regions, each resonator element including at least one ring-like resonance unit, each resonance unit being defined by at least one conductor line having at least one capacitive area and at least one inductive area, wherein a first end of one conductor line is placed adjacent to one of a second end of the conductor line and a first end of another conductor line included in the same resonance unit, in one of a width direction and a thickness direction, to define the at least one capacitive area of each resonator element.
