Abstract
The design and construction of radio frequency energy harvesting system (RF-EH) with of a 2.45 GHz specifically for Wi-Fi spectrum applications is presented in this paper. The proposed RF-EH system integrates three primary components: a circular-shaped microstrip antenna array, an equal-power combiner, and an FR-4 based RF-to-DC rectifier circuit. the antenna array was specifically built to improve signal reception, attained a measured gain of 15.8 dBi, while The rectifier offered effective RF-to-DC conversion with a peak power conversion efficiency of 24.03% at an input power of 1.3 dBm. These elements work together to efficiently capture ambient Wi-Fi signals and make it evident that low-power wireless sensor and Internet of Things devices can be powered by such systems. This energy harvesting system (RF-EH) has the potential to be a viable and useful alternative energy source for next-generation wireless communication applications because of its small size, reliance on the inexpensive FR-4 substrate, and smooth integration of antenna and rectifier design.
