<P>PROBLEM TO BE SOLVED: To improve antenna performance when a housing is formed into a double swing structure and structured to arrange an antenna element in a hinge. <P>SOLUTION: A mobile wireless device includes a first housing 11, a second housing 12, and a third housing 13 including the hinge for rotatably connecting a first housing 11 and a second housing 12 to each other. The hinge has the double swing structure including a first hinge 16 opening and closing in a housing long-side direction, and a second hinge 17 opening and closing in a housing short-side direction and comprising a conductive member. In the structure where the antenna element 18 is arranged in the third housing 13, the second hinge 17 functions as the ground of the antenna element 18, and a second radio circuit 26 of a second circuit board 14 is connected to the first hinge 16, the mobile wireless device further includes a power feed circuit 27 connecting the first hinge 16 to the second hinge 17, and a power feed circuit 35 connecting the first hinge 16 to the antenna element 18. <P>COPYRIGHT: (C)2010,JPO&INPIT |
