“…The antenna has gain of 8.3 and 7.8dBi at 1.95 and 2.45 GHz, respectively. (Silva et al, 2020) proposed a double Patch Antenna Array (DPA) composed of two patch antennas operating at different frequencies and fabricated on a unique substrate. The first one operates at 1.8GHz for mobile communication while the second one works at 2.4GHz industrial, scientific and medical band and used for Radio Frequency Energy Harvesting.…”

In this paper, a 2.4GHz antenna array for wireless power transfer (WPT) was designed and optimized for energy harvesting using MATLAB Software. Antennas are essential communication tools in energy harvesting systems as such; they are used to transmit and receive signals. The designed antenna is a 2 x 4 microstrip array. The choice of the microstrip antenna stems from the fact that, it is a class of patch antenna which satisfies all low-level conditions for Radio frequency (RF) transmission. Array antennas are deployed to maximize the overall gain, improve signal reception and achieve excellent performance. The antenna specifications were used in the analysis of the antenna formulations. The simulation result obtained shows satisfactory parameters for energy harvesting. The maximum gain was improved from 17.0 dbi to 17.5 dbi after optimization. The reflection co-efficient was also maintained above a magnitude of -26.2db. The antenna also recorded low correlation co-efficient. With the growth of self-sustaining devices, antenna arrays for energy harvesting provides an innovative solution for ecofriendly technologies.

The main challenge faced by RF energy harvesting systems is to supply relatively small electrical power to wireless sensor devices using microwaves. The solution is to implement a new device in a circularly polarized rectenna with circular polarization sensitivity integrated with a thin-film solar cell. Its dual-feed antennas are connected to a 2 × 4 asymmetric hybrid coupler and a multi-stage voltage doubler rectifier circuit. This configuration has a 2 × 4 asymmetric hybrid coupler used to produce 4 outputs with a 90-degree waveform phase difference. The two ports can independently be connected to the wireless sensor circuit: radiofrequency harvesting of hybrid energy solar and information equipment can be carried out with these two antennas. The Dual-Feed circular patch antenna has a two-port bandwidth of 137 MHz below −15 dB and an axial ratio of less than 3 dB, with a center frequency of 2.4 GHz with directional radiation and a high gain of 8.23 dB. It can be sensitive to arbitrary polarization of the input voltage multiplier waveform to overcome uncertainty in empirical communication environments. A parallel structure is arranged with a thin film solar cell integration from the transmitter with an output voltage of 1.3297 V with a compact composition and RF energy. The importance of adopting a wireless sensor strategy with circular polarization sensitivity and integrated RF solar energy harvesting rather than a single source method makes this research a significant novelty by optimizing the analysis of multiple wireless sensor signal access.

“…After the individual characterization of each element of the rectenna (antenna and rectifier), it is necessary to characterize the assembled QYR. For this purpose, a measurement setup was implemented inside an anechoic chamber, employing a CW transmission signal at 2.45 GHz with linear polarization [37] . The average power density (SAV) was adjusted from 0.05 to approximately 6 μW/cm 2 , for a link distance of 40 cm, which is sufficient to reach the far-field zone from the transmission antenna (an identical QY) and the elements were orientated to guarantee a line-of-sight propagation in co-polarization.…”

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.
