Abstract
A wireless power system may use a wireless power transmitting device to transmit wireless power to a wireless power receiving device. The wireless power transmitting device may have microwave antennas that extend along an axis in a staggered arrangement. In the staggered arrangement, the microwave antennas are positioned on alternating sides of the axis. Each microwave antenna is elongated along a dimension that is perpendicular to the axis. Multiple antennas may overlap a wireless power receiving antenna in the wireless power receiving device. Control circuitry may use oscillator and amplifier circuitry to provide antennas that have been overlapped by the wireless power receiving antenna with drive signals. The drive signals may be adjusted based on feedback from the wireless power receiving device to enhance power transmission efficiency. The system may have a wireless power transmitting device with inductive wireless power transmitting coils.
