ABSTRACT Energy harvesting technology has received a lot of attention as the demand of long life span of energy source increase. Towards that, Rectenna (Rectifier Antenna) or Energy Harvesting system is designed in the current work and it consists of antenna, matching circuit and a rectifier circuit. Microstrip patch antenna where designed to harvest GSM signals. Single-patch antenna and array antennas are designed at 900 MHz for this purpose. The designed antenna has good return loss performance and the array antennas are designed to achieve higher gain and hence more captured energy. The design and optimizing of the performance of the proposed antenna are performed by using Computer Simulation Technology software CST studio design. The rectifier circuit is a 7 stage voltage doubler circuit using Schottky diodes and it is designed to convert the RF energy into a DC output. A matching circuit has been designed from a single stub to match the complex input impedance of the rectifier circuit to the standard 50 Ω. The design of the rectifier circuits is performed by using NI Multisim 14 software and the output voltage of rectifier was 2.283V. A single stage rectifier circuit along with matching circuit are fabricated on an FR-4 substrate.
