Design of Rectangular Shaped Rectenna for RF Energy Harvesting

Wi-Fi signals are present everywhere we go and everywhere we are and that untapped energy hasn't been harnessed to its full potential. To date, this energy is exclusively used for internet access and communication. However, energy harvesting is a possibility for the efficient use of the energy. The primary focus of this study is on obtaining usable energy from wireless transmissions. The goal of this project is to develop the first power over Wi-Fi system, compatible with current Wi-Fi chipsets that can supply electrical power to low-power sensors and other low-power devices. This paper focuses on design of retina and matching network circuit to harvest RF energy from the ambient.
