Claim:
An antenna element comprising: a substantially oblong rectangular first conductor plate spaced apart from a ground plate; a substantially rectangular second conductor plate that shares a widthwise one side of the first conductor plate and that is arranged at an angle of about 90° with respect to the first conductor plate; and a substantially rectangular third conductor plate that shares another widthwise side of the second conductor plate opposite the side shared by the first conductor plate and the second conductor plate, the third conductor plate arranged at an angle of about 90° relative to the second conductor plate and opposing the first conductor plate; a first housing accommodating the ground plate; a second housing equipped with a first antenna element; and a hinge for connecting the first housing to the second housing and holding the second housing rotatably with respect to the first housing, wherein the antenna element is provided in proximity to the hinge, the first conductor plate is electrically connected to a corner of the ground plate, and an electrical connection is made at a corner of the ground plate to electrically connect the first conductor plate to the ground plate and an electrical connection is made at a corner of the first conductor plate to electrically connect the first conductor plate to the ground plate.
