“…Notably, at a distance of 90 cm, the rectenna successfully harvested approximately 850 µW of power. This power level is substantial enough to meet the energy requirements of low-consumption loads, such as Wireless Sensor Networks (WSNs) [5,6]. The harvested voltage can be directly utilized to power sensor nodes or, more optimally, stored in a supercapacitor for subsequent delivery to the load in predetermined cycles controlled by a microcontroller circuit.…”

This paper presents the design of a compact line-ofsight rectenna system for wireless power transfer and energy harvesting applications. The proposed rectenna consists of a highly-directive Vivaldi microstrip antenna and a voltage doubler rectifier circuit assembled in the same double-sided copper fiberglass substrate. To achieve the established requirements for the antenna, a mixed optimization process is proposed by using alternately two techniques: Particle Swarm and Covariance Matrix Adaptation Evolution Strategy. In addition, to limit the rectifier output current, a buffer circuit is proposed to interface the rectifier output and the load. Finally, the proposed methodology and the designed rectenna are numerically and experimentally characterized, and the obtained results confirm the system's capacity to power low-consumption loads.

“…Para la configuración de diodo en paralelo se ha obtenido una eficiencia de conversión RF-DC mayor a 54% a partir de 0 dBm [62,79,95,102,108], mientras que para el puente de diodos se han obtenido valores superiores a 42% a partir de 5 dBm [63,80,109,110], ambas configuraciones presentaron poca desviación estándar. Con respecto al rectificador de diodo en serie [30,45,51,59,61,64,66,67,70,71,77,93,100,111] y doblador de voltaje [16, 22, 23, 25-28, 34, 39, 45, 57, 58, 68, 69, 73, 98, 101, 110, 112], presentaron una mayor dispersión en la eficiencia obtenida pero tuvieron los máximos valores de eficiencia de conversión RF-DC. Con la configuración de diodo en serie se ha obtenido una eficiencia de 42% a 3 dBm mediante la cosecha de GSM a 900 MHz y de UMTS a la vez, e implementando un acoplador de impedancia para cuatro bandas [30].…”

“…Con la configuración de diodo en serie se ha obtenido una eficiencia de 42% a 3 dBm mediante la cosecha de GSM a 900 MHz y de UMTS a la vez, e implementando un acoplador de impedancia para cuatro bandas [30]. Además, se ha obtenido un valor máximo de 83,73% cuando la potencia de entrada al rectificador era de 5 dBm [64]. Con el doblador de voltaje se ha requerido menos nivel de potencia de entrada, por ejemplo para conseguir una eficiencia máxima del 47% se precisaron -10 dBm mediante la implementación de una topología de Greinacher [112].…”

“…Con respecto a los filtros, se han implementado para prevenir que las componentes armónicas, las cuales pueden generarse por los elementos no lineales del rectificador, sean re-radiadas a la antena y aumenten las perdidas por desacoplamiento. Se han usado sus cuatro tipos, es decir, el pasa bajo [26,38,45,47,51,56,64,72,85,88], el pasa alto [17], el pasa banda [24] y el rechaza banda mediante una celda resonante microcinta compacta (Compact Microstrip Resonant Cell, CMRC) para suprimir una banda superior a la de diseño [48]. Cuando se han combinado ambos elementos, se emplea un filtro pasa bajo y un acoplador de impedancia [46,104] o un filtro pasa banda y un acoplador de impedancia [15] para obtener la mejora que aporta cada elemento.…”

“…These electric power supply limitations have led to WPT research that encompasses both near-field and far-field techniques. Radio Frequency (RF) energy harvesting [1] or robotic drones [2], [3] have both been developed for transferring electric power to soil sensors [4]- [10]. RF energy harvesting requires the rectification of space-wave signals that do not penetrate far beneath the soil surface and require a substantial time to collect enough energy to perform a function.…”

Increasing the spatial and temporal density of data using networked sensors, known as the Internet of Things (IoT), can lead to enhanced productivity and cost savings in a host of industries. Where applications involve large outdoor expanses, such as farming, oil and gas, or defense, large regions of unelectrified land could yield significant benefits if instrumented with a high density of IoT systems. The major limitation of expanding IoT networks in such applications stems from the challenge of delivering power to each sensing device. Batteries, generators, and renewable sources have predominately been used to address the challenge, but these solutions require constant maintenance or are sensitive to environmental factors. This work presents a novel approach where conduction currents through soil are utilized for the wireless powering of sensor networks, initial investigation is within an 0.8-ha (2-acre) area. The technique is not line-of-sight, powers all devices simultaneously through near-field mechanics, and has the ability to be minimally invasive to the working environment. A theory of operation is presented and the technique is experimentally demonstrated in an agricultural setting. Scaling and transfer parameters are discussed. Keywords-Wireless power transfer, Through the Soil, Long Range, conduction I. INTRODUCTIONDecision making based on real-time/measured data is critically important to boosting revenue/productivity in many industries. Sensor installation throughout the industrial process plays a fundamental role in these tools. The number of sensors that can be installed is limited by two primary factors: (1) the cost (including installation/maintenance) of the sensor and Manuscript received Month xx, 2xxx; revised Month xx, xxxx; accepted Month x, xxxx.
