<p><P>PROBLEM TO BE SOLVED: To provide a mobile wireless apparatus for reducing deterioration in an antenna performance and ensuring a high antenna performance in the configuration wherein a plurality of cases are connected via a hinge. <P>SOLUTION: A frame 1 provided to an upper case 9 is connected to a hinge metallic fixture 5 of the hinge 2 and electrically conducted to a circuit board 4 via the hinge metallic fixture 7, a cylindrical conductor 7, a rotary shaft 8, and a feeding metallic fixture 3. Power is applied to the frame 1 from the circuit board 4 via the feeding metallic fixture 3 so as to act the circuit board 4, the hinge 2 and the frame 1 like a kind of a dipole antenna. A conductor plate 14 is arranged at an end opposite to the feeding metallic fixture 3 of the cylindrical conductor 7 in the vicinity of a connection cable 15 at a prescribed interval from the cylindrical conductor 7, and the conductor plate 14 is electrically connected to a ground pattern on the circuit board 4. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
