<P>PROBLEM TO BE SOLVED: To provide a feeding system that can supply power from a feeding section to a receiving section with high efficiency even if a feeding helical coil and a receiving helical coil experience a distance variation or a lateral shift. <P>SOLUTION: A feeding section 3 installed on a road has a feeding loop antenna 6 supplied with power and a feeding helical coil 7 electromagnetically coupled to the feeding loop antenna 6. A receiving section 5 installed on an automobile has a receiving helical coil 8 electromagnetically resonant with the feeding helical coil 7, and a receiving loop antenna 9 electromagnetically coupled to the receiving helical coil 8. The receiving loop antenna 9 is divided into two L-shaped members 91, 92, and the L-shaped members 91, 92 can be moved for changes in contact position to implement a variable loop size. <P>COPYRIGHT: (C)2012,JPO&INPIT |
