<P>PROBLEM TO BE SOLVED: To provide an antenna capable of coping with electric power transmission and various communications in a high-frequency band from several megahertz to tens of megahertz, having a stable electric power transmission function, and simultaneously reducing a radiation noise radiated from the antenna to exterior of an electric power transmission device at charging, and to provide an electric power transmission device and an electric power reception device using the antenna. <P>SOLUTION: An antenna is used in a non-contact electric power transmission and communication system that performs non-contact electric power transmission and communication between an electric power transmission device and an electric power reception device via the antenna. The antenna has a complexed planar coil 10 consisting of: a first terminal 13; a first planar coil 11 wound clockwise using the first terminal 13 as one end; a second terminal 14 provided at an end edge of the first planar coil 11; a second planar coil 12 wound anti-clockwise using the second terminal 14 as one end; and a third terminal 15 provided at an end edge of the second planar coil 12. <P>COPYRIGHT: (C)2012,JPO&INPIT |
