ABSTRACT: There are several sources of energy recovery in the ambient environment.
The radiofrequency energy harvesting system
is used to harvest the electromagnetic energy in the air by processing energy
sources to charge low-power electronic devices. Rectenna termed as a rectifying antenna is a device that is used to
convert electromagnetic waves in the air into direct electric current. In this
work, we have designed firstly the patch antenna with a small size printed on
the FR4 substrate (40 mm × 47.5 mm × 1.6 mm) and then the rectifier
circuit. This rectenna is capable of working at a frequency range of 2.45 GHz.
The antenna was designed using High Frequency Structure Simulator (HFSS) 13.0
software with the result of working frequency of 2.453 GHz, S11 (Return Loss) -52 dB, Voltage Standing Wave Ratio (VSWR)
1.036, gain 3.48 dB and bandwidth 150 MHz. The efficiency of rectifier design
on Advanced Design System (ADS) 2011 software is 54% at the input power of 0
dBm at 2.45 GHz. The resulting system is capable of producing electrical energy to power
low-power electronic equipment at a DC voltage of 732 mV.
