Abstract

Abstract. Renewable energy is a form of energy produced from natural resources. Besides coming from nature, renewable energy can also be obtained from electronic devices that emit electromagnetic waves. Electromagnetic waves can develop and be used as a source of power, especially low power consumption equipments such as sensors. One method that can be used to harvest the electromagnetic waves is by the method of Energy Harvesting using microstrip antenna. Energy Harvesting is one of green technologies that rapidly evolving nowadays. This study aims to design a microstrip antenna for harvesting energy with 1x2 parallel array configuration and ISM (International Standard for Mobile communication) frequency operation of 2.4 GHz. The antennas performance is based on the value of Voltage Standing Wave Ratio (VSWR), Return Loss (S11), gain and radiation pattern. The antenna design is simulated by Ansoft HFSS v.13. The simulation results is compared with the measurement results to analyze the antenna performance. The results showed that VSWR and Return Loss parameters in simulation and measurement have different performances, but still in tolerance performing range. The simulation antenna gain obtained 2.52 dB.
