Abstract: One of the main challenges in implementing sensor devices for internet of things (IoTs), is the means for the operating power supply. RF energy harvesting (RFEH) presents a promising solution as RF power is a suitable choice particularly for cases where solar harvesting is not feasible. However, in spite of RF communication system design being a well-established, there are several challenges poised for the implementation of the RFEH systems especially for harvesting the ambient RF signals. The challenges can b… Show more

“…Prior to it, complete illustration about the microwave antennas in RF energy harvesting are presented with complete design perspective. A comparative study along with performatory analysis of microwave antennas are presented in Table ; keeping intact with rectenna characteristics: operating frequency, realized gain, polarization diversity, input power levels, and RF‐to‐DC power conversion efficiency, which was not in the scope of review papers for RF energy harvesting available in the open literature. Technically, to pursue clear understanding about tradeoffs of modern RF systems; five different cases of planar antennas (monopole antennas) at different bands with reflector surfaces and integrated with rectifier circuits are designed, simulated and analyzed by using FDTD domain solver (CST microwave studio) and circuit solver (advanced design system).…”

“…In recent years, scientific studies on the potential application areas of metasurfaces have increased. The so‐called two‐dimensional MTMs, metasurfaces have very powerful capabilities to achieve versatile functionalities such as excellent absorption, abnormal reflection, polarization, sensing, energy harvesting, and cloaking . The reflection and transmission characteristics of the unit cells designed for previous metamaterial and metasurface studies are usually fixed.…”
