Claims20
A resonator device comprising:
- a mounting substrate having a conductor formed thereon;
- a dielectric substrate mounted on the mounting substrate;
- and
- a plurality of resonance units formed on the dielectric substrate, each resonance unit having a plurality of conductor lines forming a capacitive area and an inductive area in a ring shape,
- wherein the capacitive area is formed such that end portions of the plurality of conductor lines of each resonance unit of the plurality of resonance units are made close to each other in a width direction on the dielectric substrate,
- the capacitive areas of each of the resonance units are disposed such that a direction of electric-field vectors generated in the capacitive areas is uniform, and
- the inductive area is formed by a portion of the conductor lines, except for the capacitive area of the conductor lines formed on the dielectric substrate, and the conductor formed on the mounting substrate.
