Title:
WIRELESS POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/168376
Kind Code:
A1
Abstract:
A wireless power transmission system 1 is provided with: a structure entirely enclosed by an electromagnetic-wave blocking member 2 having appropriate electrical conductivity; at least one power transmission unit 3; and at least one power receiving unit 4. The power receiving unit 4 comprises a power receiver provided with, for example, power receiving antenna wiring 10 and a rectifying circuit 11. The power receiving antenna wiring 10 has: two wiring structures that are formed on the same plane, that each have one end connected to the rectifying circuit 11, and that have the other ends serving as open ends 12 arranged so as to be oriented towards each other; and a plurality of bent sections at the wiring structures. As viewed from a direction orthogonal to a direction in which wiring sites delimited by the bent sections extend, at least three pairs of wiring sites each face each other. The pair of wiring sites having the longest portions facing each other (e.g., a third power receiving antenna wiring section 14c and a third power receiving antenna wiring section 16c) are parallel to each other.
