Abstract
In each parasitic element array, each of parasitic elements has a strip shape substantially parallel to a longitudinal direction of a dipole antenna, and the parasitic elements are formed at predetermined intervals. For example, the interval is set to be equal to or smaller than ⅛ of a wavelength λ of a high-frequency signal to be fed to a feeder line. The parasitic element arrays are arranged so as to form a plurality of pseudo-slot openings that allow a radio wave from the dipole antenna to propagate therethrough as magnetic currents.
