RADIO POWER RECEIVING DEVICE FOR VEHICLE, TIRE, AND WHEEL

摘要

PROBLEM TO BE SOLVED: To provide a radio power-receiving device for a vehicle which efficiently receives radio waves from the outside and converts them into electrical energy. SOLUTION: This radio power-receiving device for the vehicle is installed with a rectenna 10 at an unsprung position of the vehicle. The rectenna 10 may be mounted inside a wheel 12 or on a member lower than a spring portion for a suspension mechanism 14. By installing the rectenna 10 at the unsprung position of the vehicle, even when the spring upper member moves vertically, accompanying the traveling of a vehicle 1, such a state that a microwave transmission antenna 104 and the rectenna 10 approach each other can be kept stable.
