<P>PROBLEM TO BE SOLVED: To maintain the radiation characteristic of a booster antenna with conduction of the booster antenna to a ground conductor. <P>SOLUTION: A power feed coil module 3 is mounted on the lower surface of a metal cover 2. A printed wiring board 8 is housed inside a cabinet 1. The printed wiring board 8 includes a ground conductor 81, a power feed pin 7, and a ground connection conductor 6. When the metal cover 2 having the mounted power feed coil module 3 is overlaid with the cabinet 1, the power feed pin 7 contacts to the connection portion of the power feed coil module 3, to electrically conduct thereto. By the contact of the ground connection conductor 6 to the metal cover 2, the metal cover is grounded to the ground conductor 81. The ground connection conductor 6 is positioned at both sides sandwiching a slit portion outside an area having the current density of an induced current flowing through the metal cover 2 from the maximum value thereof to 80%, or one of both sides sandwiching the slit portion inside the area. <P>COPYRIGHT: (C)2013,JPO&INPIT |
