Abstract: In recent years, the use of wireless devices is increasing tremendously in many applications such as mobile phones, remote sensing and many more. This has resulted in an increased demand on the use of batteries. Compared to other methods of energy scavenging,rf deals with low energy density and poses big challenges. With semiconductor and many other technologies continually struggling towards the low operating powers, batteries can be replaced by alternative sources that employ energy harvesting techniques. In this paper we present a comparative study on rfph also referred to as rf energy scavenging that includes background, system design, advantages and disadvantages and applications of rfph
