    environments, is radio frequency (RF) energy harvesting. RF energy harvesting seeks to capture ambient RF energy by means of an antenna and convert this energy to useable DC power. The presence of ambient RF energy in the environment is a result of numerous high-frequency TI RFD-ASSY-01 – Microwave Energy Harvesting System. They say: "The assembly can produce up to 60mA continuous current and ~40% RF-DC conversion efficiency into a 1kOhm load from 18dBm…29dBm input power at 2.45GHz." [[RM: ie 60 - 800 mW input.

    With this goal in mind, French researchers sought an alternative to a single omnidirectional antenna for collecting what RF energy was present in a room, such as in a home or factory setting. They developed a system that combines six parasitic element antennas (PEAs) and RF-to-dc converter circuits to transform RF energy into dc voltage. The RF input power levels verses the output voltages at the nodes of the Villard network were recorded. The input for the voltage multiplier module was fed through an efficient matching network from an RF energy harvesting antenna which is designed at 377 О© impedance. For a received signal of -27dBm (1.99) ОјW at the antenna modules produce a DC output voltage of 2.1 V across 100 kО© load.

    power conversion efficiency and stability of the functionality in the varying environment become the major considerations in this thesis project, the target of which is to design a DC-DC converter for energy harvesting applications. The conventional PWM control is not usually suitable for the DC-DC converters By harvesting power from available RF energy sources, a new generation of ultra-low-power (ULP) wireless devices, such as IoT sensors, can be developed for low-maintenance applications like remote monitoring. Energy harvesting is considered very much a “companion” technology to wireless communications, since it can enable extended battery lifetime for mobile devices and possibly battery …
