Abstract
This disclosure provides systems, methods and apparatus for forward link communication in wireless power systems. One aspect of the disclosure provides a wireless charging device for providing wireless power to a receiving device. The wireless charging device includes a primary transmit antenna configured to generate a wireless power field. The device further includes a parasitic antenna configured to selectively adjust a coupling between the primary transmit antenna and the receiving device. The device further includes a controller configured to control the selective adjustment of the parasitic antenna so as to communicate with the receiving device.
