This document summarizes a research paper on the design of a low-power rectenna for wireless power transfer. It discusses the analytical modeling and optimization of individual rectenna elements, including the microstrip patch antenna, Schottky diode model, and output filter. Simulation and experimental results show that directly matching the rectifier impedance to the antenna improves efficiency over traditional designs using a coupling capacitor. Optimizing the output filter also reduces harmonic power dissipation, further improving efficiency. The rectenna efficiency is found to increase with higher input power levels as discussed.
