    The document summarizes a student project to design a wireless power transmission system using radio frequency (RF). The goals were to research efficient wireless power mediums, select 2.4 GHz frequency, and design an RF rectenna to convert RF to DC power and wirelessly power a small device. Simulation of the rectenna design in AWR showed 55% efficiency. A microstrip rectenna was fabricated on PCB with a 2.4 GHz patch antenna, schottky diode, and matching elements. Initial testing was unable to sufficiently rectify RF power to illuminate an LED due to noise distortion. The design will be reevaluated in the next phase, and the project provided useful learning.
