“…At present, there is a great demand for the development of systems that use energy more efficiently and for new sources of energy, even if destined to feed small loads. In this context, the concept of energy harvesting is applied using different sources, such as near electromagnetic field [1,2], solar [3], piezoelectric [4], and Seebeck effect [5].…”

Nowadays, due to the ever-increasing number of electronic devices and communication systems that use high-frequency electromagnetic waves, a significant level of electromagnetic energy is available in the environment that is not entirely used. In this work, a complete electromagnetic harvesting system using a rectenna is proposed to collect this energy and feed a temperature measurement module. The rectenna is constituted by a combination of a microstrip antenna that captures the electromagnetic energy and a rectifier circuit that converts it into electric energy in direct current (DC) form to feed ultra-low-power loads. The proposed system uses a rectangular microstrip antenna, designed and optimized by using the Computer Simulation Technology (CST R ⃝ ) software to operate at 2.45 GHz. This designed antenna presents a measured reflection coefficient lower than −20 dB at the operating frequency with a maximum gain equal to 7.26 dB. In addition, a voltage doubler rectifier circuit is designed and optimized by using the Advanced Design System (ADS R ⃝ ) to match the impedance of the designed antenna to reduce the reflection losses between these two modules, achieving maximum measured efficiency of approximately 33%. Furthermore, a boost converter circuit is designed for the power management between collected and delivered powers to the sensor and to provide appropriate voltage levels to feed the temperature measurement module. This module consists of an ultra-low-power microcontroller and a temperature sensor that operates in the range of 1.8-3.6 V. The procedures for designing and testing each module of this system are detailed. Finally, a prototype is built and tested under different operating conditions to confirm its functionality and feasibility. These tests show that the proposed system can operate without batteries, only with the harvested electromagnetic energy dispersed in the environment, even from modulated and pulsating sources, as is the case of commercial routers.

“…1, the signal bandwidth and its Power Spectrum Density (PSD), associated with the narrow bandwidth of the rectifiers and their nonlinear behavior, make the characterization of the rectennas source-dependent. Thus, the use of rectennas for RFEH from indoor communication systems signals to power LPWAN devices has different concerns than those involved in the RFEH from CW signals [5] , [21], [22], which represents an ideal WPT scenario. For instance, WiFi, which is in fact the Wireless Local Area Network (WLAN) technology used today, is specified in different ways within the IEEE 802.11 standard, each employing different transmission powers, data rates, modulation and encoding techniques, bandwidths and PSDs and, therefore, causing different impacts on the performance of the rectenna and, consequently, of the RFEH system.…”

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.
