WIRELESS POWER TRANSMISSION SYSTEM
First Claim
1. A wireless power transmission system comprising:
- a power transmission antenna configured to output a microwave from an output plane;
a power reception antenna arranged in a position opposing to said output plane of said power transmission antenna in power transmission and configured to receive the microwave outputted from said power transmission antenna by an input plane; and
a shield section configured to electromagnetically shield a space between said power transmission antenna and said power reception antenna from an external space by a plurality of outer circumference coil springs provided in an area which surrounds said output plane of said power transmission antenna.

Abstract
It is desired to provide a wireless power transmission system which it is possible to more surely prevent the leakage of a microwave. A wireless power transmission system includes: a power transmission antenna configured to output a microwave from an output plane; a power reception antenna arranged in a position opposing to said output plane of said power transmission antenna in power transmission and configured to receive the microwave outputted from said power transmission antenna by an input plane; and a shield section configured to electromagnetically shield a space between said power transmission antenna and said power reception antenna from an external space by a plurality of outer circumference coil springs provided in an area which surrounds said output plane of said power transmission antenna. The coil spring bends along a convex section compared with a wire member when there is the convex section in a hit part. Therefore, good electromagnetic wave shield efficiency is obtained.
