Abstract
A foldable portable radio terminal comprising an upper housing, a lower housing and a hinge for connecting housings is provided, where an antenna is arranged adjacently to the hinge in the lower housing. A connection unit which connects an upper-housing circuit and a lower-housing circuit has a wiring length longer than a spacing between the upper-housing circuit and the lower-housing circuit. The connection unit has an inductance provided by a portion partially rolled up in spiral or in coil, which acts as a load impedance to a high-frequency current generated on the housing. The current that degrades antenna characteristics is reduced, and therefore the characteristics are improved.

A foldable portable radio terminal having a first housing for including a first circuit unit inside and a second housing for including a second circuit unit inside, said first and second housings are connected through the intermediary of a hinge so as to rotate around said hinge, said terminal comprising:
- power-supply means for supplying power to said first and second circuit units;
- and
- connecting means for electrically connecting said first and second circuit units,
- wherein said connecting means having a prescribed shape and length, so that said connecting means generates an inductance which serves as a load to a high-frequency current.
