Document Type and Number:
Japanese Patent JP5514325
Kind Code:
B2
Abstract:
In each parasitic element array (6), each of parasitic elements 5 has a strip shape substantially parallel to a longitudinal direction of a dipole antenna (4), and the parasitic elements are formed at predetermined intervals (L5). The interval (L5) is set to be equal to or smaller than 1/8 of a wavelength » of a high-frequency signal to be fed to a feeder line (20). The parasitic element arrays (6) are arranged so as to form a plurality of pseudo-slot openings (S6) that allow a radio wave from the dipole antenna (4) to propagate therethrough as magnetic currents.
