RF energy harvesting

Abstract

The current industrial landscape is becoming increasingly filled with attempts to optimize management and energy use for all domains, including telecommunications. Radio frequency (RF) harvesting topologies and energy conversion have gained more interest for operating low-power devices. By eliminating the need for batteries, this technology is a promising alternative with reliable power-constrained wireless networks to extend the lifetime. The wireless transmissions concept began almost a century ago. By using RF energy-harvesting circuits, RF energy can be harvested, however these harvesting circuits are mainly designed to operate with low currents and voltages. Thus, the discussion of various designs of antennas in harvesting RF energy is included, including the results from various survey papers. RF power-harvesting's recent applications are outlined at the end of the chapter. This chapter will serve as a good reference covering new research topics in the field of RF energy harvesting for researchers.
