Abstract
A planar antenna includes a substrate formed of a dielectric; a distributed constant line formed on a first surface of the substrate, the distributed constant line including a first end to which power is supplied and a second end that is an open end or is grounded; and at least one first resonator arranged on the first surface of the substrate and within a range in which the at least one first resonator is allowed to be electromagnetically coupled to the distributed constant line in a vicinity of any of nodal points of a standing wave of a current that flows through the distributed constant line in response to a radio wave having a certain design wavelength radiated from the distributed constant line or received by the distributed constant line.
