Abstract:
1. A resonator comprising: a top-surface ground electrode; a first high-impedance wiring, arranged parallel to the top-surface ground electrode; a second high-impedance wiring, arranged so as to face the first high-impedance wiring, each of the first high-impedance wiring and the second high-impedance wiring formed as a plate-like structure; a first columnar conductor electrically connecting the first high-impedance wiring to the second high-impedance wiring; a first low-impedance wiring arranged between the first high-impedance wiring and the second high-impedance wiring and having an impedance lower than that of the first high-impedance wiring; a second columnar conductor electrically connecting the first high-impedance wiring to the first low-impedance wiring; a second low-impedance wiring arranged between the first low-impedance wiring and the second high-impedance wiring and having an impedance lower than that of the first high-impedance wiring; and a third columnar conductor electrically connecting the second high-impedance wiring to the second low-impedance wiring.
