Compact & Efficient Single Band Antenna for 2.4GHz Rectenna in IOT Applications

This study explores the various aspects of an RF energy harvester operating at a frequency of 2.45 GHz, specifically utilizing a Microstrip Patch Antenna. The primary objective is to design, simulate, fabricate, and test a rectenna system. The emphasis is placed on the advancement of both the antenna and rectifier circuit in our proposed solution. The recent trends on modern research are extremely focusing on the energy harvesting for wide variety of applications, here as the energy needs increases, the natural resources diminish. This design provides a high-level overview of the rectifying antenna (rectenna) system. Thanks to recent technological advancements, the efficiency of RF energy harvesting has seen significant improvement. This technology presents a promising, maintenance-free alternative to traditional battery technology, which is not only costlier but also demands regular maintenance. Moreover, RF energy harvesting has the potential to serve as a backup generator for certain power systems, thereby enhancing reliability by preventing interruptions. A Microstrip Patch Antenna has been created using a rectangular shape and constructed with FR4 epoxy substrate material. The antenna utilizes a substrate with a dielectric constant of 4.4 and aims to enhance both gain and efficiency at a specific frequency of 2.45 GHz. The design process employed a contemporary method known as “Parametric Analysis.” The simulation and analysis of the antenna were carried out using Ansoft HFSS 13 software.
