Title:
WIRELESS POWER SYSTEM AND METHOD
Document Type and Number:
Japanese Patent JP2012135205
Kind Code:
A
Abstract:
To enable an antenna to maintain resonance with high Q in a wireless energy transfer system.
To maintain high-Q resonance matching, a matching circuit is formed e.g. by connecting a tunable capacitor 504 to a coupling loop 500, thereby increasing efficiency of wireless power transmission.
