Abstract
A wireless power transmission system includes a plurality of power transmitting antennas, a plurality of power receiving antennas, and a combiner configured to combine power transmitted to the power receiving antennas. At least one of a group of the plurality of power transmitting antennas and a group of the plurality of power receiving antennas is translated in a first direction relative to the other. During the translation, at least one of the power receiving antennas and at least one of the power transmitting antennas are coupled by one of an electric field and a magnetic field.
Claims11
A wireless power transmission system comprising:
- a plurality of power transmitting antennas including a first power transmitting antenna extending in a first direction and a second power transmitting antenna extending in a second direction, the plurality of power transmitting antennas being arranged in the first direction;
- a plurality of power receiving antennas including a first power receiving antenna and a second power receiving antenna, the plurality of power receiving antennas being arranged in the first direction;
- and
- a combiner configured to combine power received by the first power receiving antenna and power received by the second power receiving antenna, wherein
- at least one of the plurality of power receiving antennas and at least one of the plurality of power transmitting antennas are coupled by one of an electric field and a magnetic field,
- a length of each of the first power receiving antenna and the second power receiving antenna in the first direction is less than an interval between the first power transmitting antenna and the second power transmitting antenna that are arranged in the first direction, and the length of the first power receiving antenna in the first direction is less than a length of the first power transmitting antenna in the first direction,
- the length of the second power receiving antenna in the first direction is less than a length of the second power transmitting antenna in the first direction,
- a sum of the length of the first power receiving antenna in the first direction and an interval between the first power receiving antenna and the second power receiving antenna is greater than the interval between the first power transmitting antenna and the second power transmitting antenna that are arranged in the first direction, and
- the interval between the first power transmitting antenna and the second power transmitting antenna in the first direction is one tenth or more of the lengths of the first power transmitting antenna and the second power transmitting antenna in the first direction.
