Document Type and Number:
WIPO Patent Application WO/2022/168401
Kind Code:
A1
Abstract:
A wireless power transmission system 1 comprises: a structure body entirely surrounded by an electromagnetic wave shielding member 2 having an appropriate electrical conductivity and frequency selectivity; at least one power reception unit 3; at least one power transmission unit 4; and at least one resonance frequency adjustment unit 5. The resonance frequency adjustment unit 5 is provided with at least one conductive protruding portion 15 having an open end; and a transmission line 16 connected to the other end of the conductive protruding portion 15 opposite to the open end. The open end of the conductive protruding portion 15 is located inside the structure body, and the other end of the transmission line 16 opposite to a connecting portion to the conductive protruding portion 15 is electrically connected to the electromagnetic wave shielding member 2 that forms a wall surface of the structure body.
