<p><P>PROBLEM TO BE SOLVED: To provide a foldable mobile phone wherein an upper case circuit board and a lower case circuit board act like a second antenna in addition to a first antenna, inter-component mutual coupling between the antennas is eliminated to prevent deterioration in the characteristic. <P>SOLUTION: An antenna connection switch 130 is provided between a feeder line 131 of the second antenna 13 comprising the upper case circuit board and the lower case circuit board and a matching circuit 132 of the second antenna. Further, when the first antenna 12 is selected, the antenna connection switch 130 is opened to deactivate the second antenna 13 thereby preventing the deterioration of characteristics of the first antenna 12. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
