Besides 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 equipment such as sensors. One method that can be used to harvest the electromagnetic waves is of Energy Harvesting method using microstrip antenna. Energy Harvesting is one of the green technologies that are rapidly evolving nowadays. This study aims to design a microstrip antenna to harvest energy with 1x2 parallel array configuration and ISM (International Standard for Mobile communication) frequency operation of 2.4 GHz. The antenna's performance is based on the value of Voltage Standing Wave Ratio (VSWR), Return Loss (S11), gain and radiation pattern. Ansoft HFSS v.13 simulates the antenna's design. The simulation results are 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 intolerance performing range. The simulation antenna gain obtained 2.52 dB. ## Keywords - Standing wave ratio - Antenna (radio) - Return loss - Electrical engineering - Microstrip antenna - Antenna measurement - Antenna factor - Microwave - Patch antenna - Radiation pattern - Renewable energy - Acoustics - Engineering - Telecommunications - Physics --- Sumber: Discover Unhas — RIMS Universitas Hasanuddin.
