“…3a. This rectifier is often addressed in the literature [5] , [26] , [27] and it presents a higher efficiency when compared to voltage multiplier rectifier topologies, for low input power levels (Pin) [25]. Additionally, when it is compared with more complex rectifier topologies, as voltage doubler and full wave rectifiers, it requires a lower number of components, also contributing to decrease the prototype cost.…”

This article presents an experimental analysis of the use of signals transmitted by Wireless Local Area Networks (WLAN) based on the IEEE 802.11b/g standards for Radio Frequency Energy Harvesting (RFEH) applications in indoor environments employing a Quasi-Yagi Rectenna (QYR) topology. This analysis is a crucial point to distinguish the use of the IEEE 802.11b/g standards for ambient RFEH applications and contributes to the debate on the use of different types of energy available for free in modern society. For it, a dedicated setup, developed in a controlled environment to avoid any external interference, was built to carry out the programmed measurements. The results obtained indicate that IEEE 802.11b/g standards have great potential for applications in RFEH, with the IEEE 802.11b average power four times higher than IEEE 802.11g at the rectifier output.

“…This topology was chosen due to its simplicity and operational characteristics in the desired band [18] , [19] . The Schottky diode (D) SMS7630-079LF by Skyworks is used due to its low zerobias junction resistance and capacitance, inversely related to the diode's efficiency [20] . The output capacitance C (100 pF) and the output inductance L (10 μH) compose the output Low-Pass Filter (LPF), which is responsible for the output voltage (Vout) suppression [21].…”

This paper presents a patch antenna array topology for Simultaneous Wireless Information and Power Transfer (SWIPT) applications. The resulting Double Patch Antenna Array (DPA) is composed of two patch antennas operating at different frequencies and fabricated on a unique substrate. One of the patches operates at the 1.8 GHz mobile communication band and is used for wireless communication, while the other one operates at the 2.4 GHz Industrial, Scientific, and Medical (ISM) band, and is used for Radio Frequency Energy Harvesting (RFEH). The analyzes and measurements carried out have shown that the adopted topology has satisfactory performance for communication, with a gain of 1.5 dBi, and for out-of-band energy harvesting, with a Vout of 160 mV at 2.45 GHz. These results indicate this approach as a promising strategy for low-power wireless applications.

“…This model adopted a discrete multi‐objective optimisation paradigm to retrieve the Pareto front under interference and spatial illumination constraints. Silva et al [23 ] enforced radio frequency power harvesting from the environment to generate a continuous energy supply implemented with various integrated circuit topologies with maximum output voltage. They utilised genetic algorithm technique to accomplish the bi‐objective optimisation process of high‐output voltage and circuit efficiency with the energy harvesting capabilities.…”

Sustainable operation of energy-restrained wireless network services requires multiple objectives to be satisfied synchronously. Among these objectives, reduced spectrum outage, energy conservation, and minimal packet transmission failures considerably affect the energy harvesting operation of these networks. These three objectives are associated with disparate protocol layers incorporating the transport, medium access control, and physical layers of traditional networking architecture. The authors investigate energy harvesting wireless communications by formulating the multi-objective optimisation problem comprising these global networking criteria, which are simultaneously optimised with the heuristic design procedure. For this, they employ a Pareto-based evolutionary genetic algorithm technique built in the wireless network design and operation to find the optimal set of all non-dominated solutions traversing the entire design search space. Besides, iterative implementation of the presented genetic optimisation model with distinct feasible integrations of crossover and mutation operations is performed to evaluate the proficiency of the proposed scheme for evaluating the Pareto-optimal frontier set. The influence of different combinations of these operations is examined and adaptively applied with appropriate genetic parameters tuning for efficient meta-heuristic search through the candidate solution space. Simulation results demonstrate that the proposed hybrid genetic mechanism outperforms the existing methods in terms of throughput, energy efficiency, and loss rate.
