Patent ID: 6972645

Claim:
A resonator comprising: a substrate having a surface; a conductive film provided on the surface of the substrate, the conductive film having conductor opening portions at predetermined positions, the conductor opening portions including at least two inductive regions and at least one capacitive region, the at least one capacitive region interconnecting the inductive regions; and at least one resonator element 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.
