  • Patent number: 7369883
    Abstract: A radio communication device comprises an upper housing and a lower housing connected by a hinge part to be mutually rotatable. A connection portion electrically connects a first circuit board in the upper housing and a second circuit board in the lower housing each other. An antenna is provided in the lower housing and has a base, an electric supply terminal and a ground terminal. An antenna electric supply part is provided to supply an operating current from the second circuit board to the antenna. A position of the antenna electric supply part is shifted from a central position of the second circuit board in an axial direction of the hinge part to increase a distance from the connection portion, and the electric supply terminal and the ground terminal are extended from the antenna base in the hinge part axial direction to contact the antenna electric supply part.
