Abstract

Renewable Energy sources are the center of attraction for research and
development all over the world nowadays. Oil and Gas are no more the main
source of Energy, consequently the demand of a lasting cheap source of energy
that is environmental friendly, is the main challenge recently.
During the last decade, power consumption has decreased opening the
field for energy harvesting to become a real time solution for providing different
sources of electrical power.
Energy Harvesting is a new technology that is going to make a revolution
in the coming decade. Energy Harvesting is a technique to provide alternative
sources of energy that are environmental friendly and low in cost.
Radio Frequency Energy Harvesting is one of the methods to provide
electrical energy from the ambient Radio Frequency Energy that already exists in
the environment. For example Hand phones can be directly charged from Radio
frequencies in the environment like 915 MHz. Laptops can be charged by
frequencies like 2.45 GHz. RFID passive tags can be powered by these radio
frequencies without the supply of any batteries increasing the range of passive
RFID tags to longer distances with lower cost.
Radio Frequency Energy Harvesting can provide a world with batteryless
devices. With RF Energy Harvesting, the true mobility can be achieved where
mobile devices do not depend on centralized power sources for charging. Instead
they make use of the existing energy in the environment.
