ABSTRACT:
There is provided a radio apparatus having a built-in type antenna of a broad frequency range in a thin case. The radio apparatus comprises a fist case containing a first printed circuit board (PCB) and a second case containing a second PCB. The two cases are joined by a hinge part. A radio circuit is contained in the first or the second case or the hinge part, and is connected to a first end of a feeder line including a signal line and a return line. A first antenna element formed as a printed pattern of the first PCB is connected, by a first conductor, to the signal line at a feeding point, i.e., a second end of the feeder line. A second antenna element formed as a printed pattern of the second PCB is connected, by a second conductor, to the return line at the feeding point.
