Abstract
Parasitic elements of each parasitic element pair have a strip shape, and are formed on a straight line, which is parallel to a longitudinal direction of a printed dipole antenna and is positioned in a radiation direction of radio wave from the printed dipole antenna, so as to have a gap of a predetermined interval. The parasitic element pairs and the dipole antenna are arranged at predetermined intervals so as to oppose to and to be electromagnetically coupled to each other.
