PROBLEM TO BE SOLVED: To provide a downsized antenna system that is manufactured with simple manufacturing processes and mounted even on a mobile communication apparatus having a broadband characteristic or a high sensitivity reception characteristic, and a terrestrial digital broadcast reception function. SOLUTION: An antenna pattern 3 including many loopback parts 100 configuring multiple loops wherein magnetic field energy stored inside, is prioritized over electric field energy is formed on at least one principal side of a board 2. The board 2 is formed by a board material obtained by mixing a magnetic material with dielectric material, and the wavelength of the antenna pattern 3 is reduced. COPYRIGHT: (C)2006,JPO&NCIPI
