ANTENNA, ELECTRIC POWER TRANSMISSION APPARATUS, POWER RECEIVING APPARATUS AND A CONTACTLESS ELECTRIC POWER TRANSMISSION SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide an antenna capable of changing an inductance of a coil. PSOLUTION: The antenna includes: an antenna element 21 in which a conductive pattern 27 is formed and constructed in loop and at least partial parts 27a, 27b of the conductive pattern 27 are formed in parallel with each other; a capacitor 22 provided in the conductive pattern 27; a pair of contact pieces 23, 24 coming into contact with the parallel parts 27a, 27b, respectively; and a slide mechanism 25 for changing contact positions of the pair of contact pieces 23, 24 relative to the parallel parts 27a, 27b by simultaneously sliding the pair contact pieces 23, 24 along the parallel parts 27a, 27b.
