Patent ID: 8265718

Claim:
A flip mobile radio device in which a first housing and a second housing are coupled rotatably by a hinge part to open and close, the flip mobile radio device comprising: a first circuit board which is provided inside the first housing; a second circuit board which is provided inside the second housing and on which a radio circuit is mounted; a conductive hinge which is provided in the hinge part; a power feeding section which is provided inside the first housing and which feeds power to the conductive hinge from the first circuit board; and a capacitive coupling element which is provided inside the second housing, and which comprises an elongated part that is capacitive-coupled to a part of the conductive hinge, through a capacitive coupling part arranged to face the part of the conductive hinge, that is connected to a ground pattern of the second circuit board, in a position apart from the capacitive coupling part along an axial direction of the conductive hinge and that short-circuits the capacitive coupling part and the ground pattern.
