Title:
POWER-RECEIVING ANTENNA
Document Type and Number:
WIPO Patent Application WO/2015/163296
Kind Code:
A1
Abstract:
A power-receiving antenna includes: a first conductor (21) which a Z-axis magnetic flux intersects; a second conductor (22) which an X-axis magnetic flux intersects; a third conductor (23) which a Y-axis magnetic flux intersects; a substrate (20); and a capacitor which constitutes an LC resonant circuit in conjunction with an inductance provided by the first conductor, the second conductor, and the third conductor. At least a part of the first conductor (21) is formed along a first principal plane or a second principal plane of the substrate (20), and at least a part of the second conductor (22) and the third conductor (23) is placed on the first principal plane of the substrate (20) so as to be erected from the first principal plane of the substrate (20). This configuration allows for receiving power even when the attitude of the power-receiving device relative to a wireless power-supplying device is indefinite.
