Abstract

There is a demand of power at remote locations
for many applications such as charging of batteries for WSN.
Due to advancement in technology, many devices operate at low
power level. The RF energy can be harvested and fed to these
devices on board. RF signal is available globally and energy can
be harvested from this signal. It is available at all times and can
be used as source of energy for low power devices. RF harvesting
unit consists of three modules, Antenna, Matching network and
Rectifier circuit. This paper presents an overview of each stage of
RF harvesting architecture. The paper introduces designed
antennas, factors affecting the different parameters of antenna
like bandwidth, gain and efficiency. Design of antenna with
miniaturization, harmonic rejection and frequency selectivity is
explained. The comparative study of matching network such as L
type, π type and microstrip line is described for maximum power
transfer and different rectifier circuits for RF to DC conversion
are discussed.
