Microwave Power Transmission to a MAV using a Software Retro-Directive System

Microwave power transmission system for a Micro Aerial Vehicle using a software retrodirective system has been studied. Power transmission demonstrated while the MAV model was circling over the transmitter antenna at the altitude of 60cm. The output voltage from the rectenna array was measured while the microwave beam was synchronized the motion of the MAV model. The out put voltages were higher than 0.2V which means the minimum requirement for operation of the electric motor on the MAV model.
