Higher efficiencies of RF-DC conversion and low power
DC-DC converter are required.
Fig.1 shows the basic block diagram of RF–DC conversion
system. Wireless networks are an omnipresent RF energy
source; therefore we have developed an RF energy harvesting
system at 2.67 and 5.8GHz. It covers the lower and upper
bounds of Wi-Max. RF-DC conversion using Schottky diode
and CMOS rectifier has been explored. Minimum numbers of
components are used in the design of the RF Energy
harvesting system to reduce power dissipation.
