ABSTRACT:
In a portable radio of the present invention, in order to reduce an influence of a flexed unit near an antenna with a structure that the antenna is fitted to a flexion portion of the unit, a conduction portion of the unit is divided into upper and lower sections interposing an antenna fitting portion. An actual resistor is inserted into the middle of an connection line (cable) for electrically connecting the upper and lower sections, thereby cutting a high frequency current. Alternatively, an inductor is inserted into the middle of the connection line (cable), thereby cutting a conduction between the upper and lower sections in a high frequency manner. The unit of the portable unit may be a structure that it is divided into upper and lower unit sections and it is foldable.
