Radio Frequency (FR) energy harvesting is a sustainable energy source method that may provide alternative resource solutions.
The increasing energy demands of the world’s population and the quickly diminishing fossil fuel reserves suggest the urgent need to secure alternative energy resources.
A prominent advantage of RF energy scavenging is the ability to convert ambient energy into electrical power throughout day and night, both outdoor and indoor. Although ambient microwave signals have very low energy compared with wind or solar, they commonly radiate energy at all times.
RF scavenging can allow for size reduction in the harvesting system in applications where miniaturization is essential. This research focuses on developing highly sensitive and efficient ambient RF energy scavenging methods and systems to generate DC power from dissipated RF signals with very low power densities.
