ANTENNA STRUCTURE AND RADIO COMMUNICATION DEVICE USING THE SAME |
摘要 |
A radiation electrode is formed on a substrate of a surface mount antenna. One end of the radiation electrode forms a ground connection portion connected to ground, and the other end of the radiation electrode forms an open end. A ground connection electrode for connecting the open end of the radiation electrode to ground via a capacitance is provided on the substrate. No feeding electrode for feeding power to the radiation electrode is provided on the substrate. This surface mount antenna is mounted on a non-ground region (a region on which a ground electrode is not formed) of a board so as to constitute an antenna structure. On the board of the antenna structure, a feeding electrode for capacitively feeding power to the radiation electrode is provided at a position between the ground connection portion and the open end.
