<p><P>PROBLEM TO BE SOLVED: To provide a portable radio device which can obtain a directional diversity effect and has high antenna performance. <P>SOLUTION: A plate-shape conductor 2 is provided on an upper case 10. On the plate-shape conductor 2, on its lower end (-Z side), a power feed section 3 is provided on the left end (-Y side), and a power feed section 4 is provided on the right end (Y side). A matching circuit 5 is connected to the power feed section 3, and a matching circuit is connected to the power feed section 4. Also, a circuit substrate 21 is disposed on the lower case 11. A radio circuit 24 is disposed on the circuit substrate 21, and any one of the matching circuits 5 and 6 is selected by a switch 23 and is connected to the radio circuit 24. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
