Abstract

An efficient antenna topology is investigated to be used for energy harvesting system design towards autonomous RFIDs and wireless sensor. Currently, the usage of autonomous and electronic device is increasing and these devices all require a battery. In order to minimizing the need of battery and realize self-powered wireless sensors, the design of proposed antenna must be able to capture as much as possible RF energy from surrounding to be used as energy harvesting system. A PCB substrate of FR-4 is used to fabricate an antenna as it is not expensive and can be obtained easily. The high gain of microstrip patch antenna array that operating at 2.45GHz at ISM Band is achieved with additional slot introduced on the rectangular patch antenna element with 14.08dB from the simulation results and 10.46dB by experiment. The minimum output power able to operate rectifier part of this harvesting system which the voltage is test to turn on LED and produce the output voltage ranging from 0.01V to 3.94V. This harvesting system shows good performance both simulation and measurement and RF to DC conversion.
