Abstract

Power source in battery nowadays have become part of human life. The short lifetime of battery sometime can be a problem. Even though nowadays, there are many others technique of energy harvesting such as solar panel, wind energy and other renewable source, but it is not convenient to use large power source to power up low power level application such as sensors and wireless tags. Therefore solution of other energy harvesting that is small yet efficient must be achieved. Rectenna is a solution to create small energy harvesting tools that can be applied to low power level application. Rectanna is basically a device that used to capture and convert signal into DC power and used as receiving terminal. Rectenna is combining of rectifying circuit and antenna. Both of rectifying circuit and antenna design will determine the overall performance of rectenna. Proposal of this project is to harvest enough energy that can power up low level application such as wireless tags at 2.45 GHz. Rectenna will be design using CST studio software and fabricated on FR4 board. RF Schootky diode will be used to construct rectifying circuit. The matching of the Schootky diode will be in stub matching form which will be design on FR4 board. The horn antenna will be used as a transmitter that resonate at 2.45 GHz for the input power level at -20dBm to 20dBm. Rectenna then will be used to convert the signal into DC voltage.
