Microstrip patch array rectenna with harmonic suppression capability for energy harvesting application

This research proposes a microstrip patch array rectenna for Radio Frequency (RF) energy harvesting at 2.45 GHz. Energy harvesting is a process where energy is derived from external sources which is captured and converted into power supply. External source being used in this research is RF energy. R...

Energy harvesting is a process where energy is derived from external sources which is captured and converted into power supply. External source being used in this research is RF energy. Rectenna is a combination of rectifier circuit and antenna. There are three stages in designing a rectenna system. The first stage is receiving antenna which is designed to have high gain and able to capture the 2.45 GHz signal. In order to yield high gain and suppress the harmonic frequency, microstrip patch array antenna is integrated with electromagnetic bandgap (EBG) and filter. The microstrip patch array antenna is etched on FR-4 substrate with thickness of 1.6 mm and the dielectric constant of 4.4. The antenna is designed and simulated using the Computer Simulation Technology (CST) Microwave Studio software. The effectiveness of the EBG and filter structure for harmonic suppression and gain improvement has been tested. The simulation and measurement results verified that the combination of the array antenna with EBG and filter is efficient in eliminating unwanted frequencies and increase the gain from 3.665 dB to 9.112 dB. In the second stage, seven stages Villard voltage multiplier circuit has been used as a rectifier circuit which converts the RF signal into direct current (DC) power supply. The rectifier is designed and simulated using Advanced Design System (ADS) software. Rectifier circuit prototype is measured and the result indicated that it can convert signal into 0.5V DC power supply. The third stage is the integration of the receiving array antenna and rectifier circuit which successfully produced 0.3V power supply.
