<p><P>PROBLEM TO BE SOLVED: To prevent an influence of electromagnetic coupling upon a coil on one face from spreading to a coil on the other face, in a device with the coils provided on both faces. <P>SOLUTION: The device is provided with: at least one first coil disposed along a first face, transferring a signal with an external coil by electromagnetic coupling; at least one second coil disposed along a second face opposite to the first face, transferring a signal with the external coil by electromagnetic coupling; and an electromagnetic coupling interfering layer provided between the first coil and the second coil, interfering with the electromagnetic coupling between the external coil on the second face side and the first coil without interfering with the electromagnetic coupling between the external coil on the first face side and the first coil, and interfering with the electromagnetic coupling between the external coil on the first face side and the second coil without interfering with the electromagnetic coupling between the external coil on the second face side and the second coil. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
