Patent ID: 8768420

Claim:
A mobile terminal having a first housing in which a first circuit board is housed, a second housing in which a second circuit board is housed, and a radio circuit mounted on the first circuit board or the second circuit board, with the first housing and the second housing being connected to each other via a connection mechanism rotatable in three-dimensional directions, the terminal comprising: a first antenna configured to receive power from a first power feed point on the first circuit board housed in the first housing; a second antenna disposed at a corner portion of the second circuit board adjacent to the connection mechanism and configured to receive power from a second power feed point on the corner portion of the second circuit board housed in the second housing; a first signal cable disposed to pass through a hollow portion in the connection mechanism and configured to electrically connect the first circuit board to the second circuit board and transmit a signal between the first circuit board and the second circuit board; and a second signal cable disposed to pass through the hollow portion in the connection mechanism and configured to electrically connect the first circuit board to the second circuit board and bypass a board current flowing through the first signal cable from the first circuit board to the second antenna during operation of the second antenna; wherein the first signal cable is connected to the second circuit board at a first connection position, the second signal cable is connected to the second circuit board at a second connection position, and the second connection position is nearer to the second power feed point than the first connection position and located in a range of ⅕ of a wavelength of a radio signal transmitted/received by the second antenna from the second power feed point, and wherein the first antenna is disposed at a corner portion of the first circuit board farthest from the second antenna, and the first and second antennas are connected to the radio circuit via the first and second power feed points, respectively, so that the radio circuit performs spatial diversity reception or pattern diversity reception of the radio signal by selectively using the first antenna and the second antenna.
