Title:
Wireless electric supply device
Document Type and Number:
Japanese Patent JP6025071
Kind Code:
B2
Abstract:
A wireless power supply device is capable of supplying constant power without fluctuation in transmission efficiency even when small-sized antennas in which the power fluctuates due to the transmission distance are used. The wireless power supply device includes a first power receiving antenna having a power receiving surface facing a power transmission surface of a first transmission antenna and a second power receiving antenna having a power receiving surface facing a power transmission surface of a second power transmission antenna, both are integrally formed and connected to a power supply target. A direction in which the power receiving surface of the first power receiving antenna faces the power transmission surface of the first power transmission antenna is parallel to a direction in which the power receiving surface of the second power receiving antenna faces the power transmission surface of the second power transmission antenna.
