Abstract

The present invention provides a portable transceiver where a broadband of an antenna characteristic can be realized and efficiency is improved. The present invention provides a portable transceiver includes a first housing (7) having a first circuit board (5) in its inside and an input section at its surface, a second housing (8) having a second circuit board (6) in its inside and a display section at its surface, and a coupling section (4) for electrically coupling the first circuit board (5) with the second circuit board (6). An antenna section (3) and an element section (9) are disposed at one of the circuit boards, and the first housing (7) and the second housing (9) are coupled with each other via a hinge section (2) and can be folded.
