Title:
無線電力直交偏波アンテナアレイ
Document Type and Number:
Japanese Patent JP6401275
Kind Code:
B2
Abstract:
Systems and methods for wireless power transmission are described herein. In one aspect, an apparatus for wireless power transmission comprises a first antenna array of antenna coils configured to generate a first wireless field. A second antenna array of antenna coils generates a second wireless field. The first antenna array at least partially overlaps the second antenna array. A driver circuit generates first and second drive signals for generation of the first and second wireless fields via the first and second antenna arrays, respectively. The first wireless field is orthogonal with respect to the second wireless field. The first antenna array and the driver circuit power the antenna coils of the first antenna array with alternating polarities. The second antenna array and the driver circuit power the antenna coils of the second antenna array with alternating polarities.
