Abstract
An antenna of a compact size enables to raise the inductance value of the resonance section and produce high gain. The antenna is constructed by connecting resonance sections and in series, in which each antenna element has an inductance section and a capacitance section connected electrically in parallel, and each inductance section has a conductor shaped in a square shape to circle the respective coil axes, and the opening sections formed at respective ends of the coil sections are contained in respective planes that are oriented at an angle to the coil axes.
