“…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).…”

“…Hence, it can be taken as the broader area of exploration for research, where RF researchers can pursue modeling of antennas through soft computing techniques. A comparative focus on recent developments of microwave antennas in RF energy harvesting [146][147][148][149][150][151][152][153][154][155][156][157][158] with concurrent analysis are shown in Table 2. The characteristics of microwave antennas are normally dealt with frequency of operation, realized gain, radiation characteristics, and antenna efficiency; followed by the properties of rectenna characterized with parameters such as input power levels, RF-to-DC PCE, and harvested voltage.…”

With the significant rise of low power embedded devices in various applications of both consumer and commercial usage, the surge for continuous power requirements has initiated promising research toward alternative sources of energy. It includes the domain of wireless power transmission, internet‐of‐things, wireless sensor nodes, machine‐to‐machine, and radio frequency identification. Thus, the overall scope of this review article is to witness microwave antennas and its implementation in RF energy harvesting system through ambient RF signals. For this reason, unified understanding of classical electromagnetism is needed; beginning with the fundamentals of RF transmission and the exploration of concepts such as Fraunhofer's Distance and Friis Transmission Equation. It is followed up by the analogy of dependency of parameters like circuit build‐up, conversion efficiencies and amount of power harvested, which is quite crucial from the rectifier point‐of‐view. For better improvisement in RF energy harvesting systems, five different cases of monopole antennas are explored with reflector surfaces such as PEC (perfect electrical conductor) and AMC (artificial magnetic conductor) integrated with the rectifier circuit. Implementation with wide diversity has proposed a generalized solution for achieving tradeoffs: polarization and pattern diversity with consistent system efficiency; leads to clean and sustainable energy for low power‐embedded devices.

“…Consequently, the design of energy-efficient transmission is of great significance for transforming the green concept into future wireless-powered IoT. Although the harvested energy from RF signals appears to be inefficient and the WPC-based wireless communication seems to be not widely available at the current stage, practical applications for power-constrained devices of IoT have already been investigated, and more feasible applications will be implemented in the near future [6][7][8]. Until now, a lot of research efforts have also been devoted to explore the advantages of WPC in most applications of IoT since it could be easily combined with wireless terminals [9][10][11][12][13].…”

In this paper, we consider the secure green-oriented multiuser scheduling for the wireless-powered Internet of Things (IoT) scenario, in which multiple source sensors communicate with a controller assisted by an intermediate sensor with the existence of a passive tapping device. Due to the limited energy, all sensors must acquire energy from external power beacons (PBs). Specifically, for the security improvement, we introduce two multiuser scheduling schemes possessing the optimal PB chosen by the relay, i.e., the best source sensor is scheduled in a random way (BSR), while the best source sensor is decided by the best PB (BSBP). Furthermore, for every scheme, we derive the analytical expressions for the secrecy outage probability (SOP) and investigate the secure energy efficiency (SEE) optimization problem with constricted transmission power in PBs. Simulation results reveal that the BSBP scheme provides better secrecy performance, and elevating the PBs quantity or reducing both the ratio of distance from PBs to source users and the total communication distance to some extent is helpful for improving SEE. In addition, the time-switching factor shows an important effect upon secrecy performance of the considered system.
