Abstract
An object is to provide a stepped impedance resonator capable of efficiently reducing a footprint. A resonator includes a coplanar waveguide and a section. The coplanar waveguide has a first impedance. The section has a second impedance different from the first impedance and includes a fishbone waveguide. The resonator is configured as a stepped impedance resonator in which the coplanar waveguide and the section including the fishbone waveguide are connected in series.
