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.
