<P>PROBLEM TO BE SOLVED: To provide a portable radio apparatus, which has a slide structure, capable of suppressing deterioration in antenna performance caused by a connection line connecting upper and lower circuit boards. <P>SOLUTION: A portable radio apparatus comprises: a lower housing 2; a first circuit board 3 installed in the lower housing 2; a power supply part 4 configured on the first circuit board 3; an antenna 5 electrically connected to the power supply part 4; an upper housing 6; a second circuit board 7 installed in the upper housing 6; and a connection line 8 for electrically connecting the first circuit board 3 and second circuit board 7, where a slip part 71 coupled with the connection line 8 at high frequency is installed on the second circuit board 7. Thereby, deterioration in performance of the antenna 5 caused by the connection line 8 can be suppressed. Installation of a slit adjustment part 12 for adjusting a coupling state between the slit part 71 and the connection line 8 on the second circuit board 7 makes it possible to suppress the deterioration in the performance of the antenna 5 caused by the connection line 8 without changing a shape of the connection line 8. <P>COPYRIGHT: (C)2013,JPO&INPIT |
