<p>A power transmitting antenna 105, which is arranged on the ground, and a power receiving antenna 107, which is arranged at the bottom of the vehicle 101, set up resonances at substantially the same resonant frequency and produce magnetic coupling between them. When the power receiving antenna 107 enters the zone in which the power transmitting antenna 105 is located, power is transmitted to the vehicle. By setting H, which is the distance between the power transmitting and receiving antennas that face each other, so that H satisfies 0.11xW1 ? H ? 0.26 x W1 with respect to the width W1 of the power transmitting antenna, the transmission characteristic can be stabilized.</p> |
