Developments And Difficulties in RFM Energy Harvesting Antenna Design and Rectifying Circuits
Main Article Content
Abstract
Energy-efficient, battery-free technologies are becoming more and more necessary as smart devices proliferate. These technologies are necessary to support IoT devices in Industry 4.0 and 5G networks, which demand minimal maintenance and sustainable operation. A carbon-free future is supported by integrating radio frequency (RF) energy harvesting with IoT and 5G technologies, which allows for real-time data collection, lowers maintenance costs, and boosts productivity. With an emphasis on low-energy device powering and far-field wireless power transfer, this overview examines the difficulties and developments in RF energy harvesting. It focuses on enhancing diode nonlinearity design while examining downsizing, circular polarization, fabrication problems, and efficiency using the metamaterial-inspired antenna. In this study, important parts such antennas, rectifiers, and impedance matching networks are examined, and their uses in biomedical and Internet of Things devices are assessed. The evaluation ends with suggestions for future.The demand for battery-free, energy-efficient solutions is rising as smart devices proliferate.
