Abstract :
A prototype rectifying antenna (rectenna) to provide wireless power transfer (WPT) to a micro-remotely piloted vehicle (MRPV) is developed. Microwave radiation at 1.3 GHz is converted into DC to drive a small motor and spin a mockup helicopter rotor blade. The rectenna serves a dual purpose as the antenna and outer body of the proposed vehicle and allows efficient reception of power over 360 degrees around the vehicle. Wireless power transfer to the mockup MRPV has been demonstrated with less than 1 watt of transmitted power at near field ranges. Rectification efficiencies up to 3046 were measured for two rectifier circuit configurations using 1.3 GHz continuous wave (CW) and pulse modulated transmitted signals
