Document Type and Number:
WIPO Patent Application WO/2013/008333
Kind Code:
A1
Abstract:
A non-contact power transmission antenna (10) is coupled by an antenna (20) and an electromagnetic field, and can receive power from the antenna and transmit power to the antenna. The non-contact power transmission antenna is provided with: a power supply unit (110); and a first antenna element (120) and a second antenna element (130), each of the antenna elements being electrically connected to the power supply unit. The first antenna element comprises a first conducting body, wound into a spiral within a given plane. The second antenna element comprises a second conducting body, wound into a spiral within the given plane, or within another plane that faces the given plane. When viewed two-dimensionally on the given plane, the region surrounded by the outer edge and the inner edge of the first antenna element has a portion that does not overlap with the region surrounded by the outer edge and the inner edge of the second antenna element.
