ABSTRACT:
A wireless communication device is arranged to be fixed to a main body of an information-processing apparatus. The wireless communication device includes an antenna, a matching unit coupled with the antenna, a high frequency circuit coupled with the matching unit, and a case for accommodating the matching unit and the high frequency circuit. The matching unit includes a ground part having a screw acceptor capable of contacting a screw. The main body of the information-processing apparatus includes a housing made of electrically-conductive material, such as metal. A first screw contacts the screw acceptor, fixes the case to the housing of the main body, and electrically connects the ground part of the matching unit with the housing. A second screw fixes the case to the housing of the main body. This wireless communication device provides the antenna with excellent characteristics.
