Abstract
A device including a processor configured to identify a power receiving device and to determine a range configuration relative to the power receiving device is provided. The device also includes a first antenna configured to emit a propagating radiation at a selected frequency and in a selected direction, and a first power transmitting circuit configured to provide a signal at the selected frequency to the first antenna when the processor identifies the power receiving device within a far field configuration from the device. The device also includes a plate, configured to couple a ground terminal of the first power transmitting circuit with the first antenna and including a planar surface and at least an extension angled in a direction of increased directivity of the propagating radiation. Methods for fabricating and using a device as above are also provided.
