WIRELESS POWER SUPPLY DEVICE
First Claim
1. A wireless power supply device comprising:
- a microwave generator for generating microwaves;
a first power transmission antenna to which microwaves generated by the microwave generator are supplied;
a second power transmission antenna to which microwaves generated by the microwave generator are supplied;
a first power receiving antenna provided between a power transmission surface of the first power transmission antenna and a power transmission surface of the second power transmission antenna, having a power receiving surface facing the power transmission surface of the first power transmission antenna; and
a second power receiving antenna provided between the power transmission surface of the first power transmission antenna and the power transmission surface of the second power transmission antenna, having a power receiving surface facing the power transmission surface of the second power transmission antenna,wherein the first power receiving antenna and the second power receiving antenna 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.

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.
