Abstract
A far-field wireless power transfer system is proposed for supplying power to remote wireless sensors. The system is mainly composed of two devices: a wireless power transmitter and a wireless power receiver. The wireless power transmitter emits 4 W of power into a directional antenna. The wireless power receiver utilizes a bi-quad antenna and L-matching network for efficient power rectification. The System is able to recover 3.3 V at a distance of 110 ft.
