“…Проте їхній високий імпеданс активної частини у діапазоні УВЧ ускладнює побудову КУ. Транзистори з діодним підключенням [77] мають напругу включення, близьку до порогової (менше 150 мВ), що дозволяє збирати енергію за дуже низької вхідної потужності. Транзистори з діодним підключенням дозволяють значно знизити площу випрямляча та зменшити вартість серійного виробництва ректен.…”

Progress in the development of rectenna systems for collecting/harvesting and converting the power of electromagnetic (ЕМ) fields created by radio-electronic means of various classes and purposes into direct current (DC) are considered. The article consists of two parts, each of which highlights important aspects of this topic. The main parameters of rectennas and the mechanisms of power loss in them are considered in the first part of the article. This allows us to understand the physical and technical limitations that have to be faced in the development of effective ЕМ power harvesting systems. The second part of the article considers typical schemes of rectennas for use in various applications. Features of the technical implementation of single-band rectennas, options for minimizing their dimensions and the construction of electrically small rectennas based on metasurfaces are given. Schemes of constructions of rectenna arrays and their advantages and disadvantages are also presented. Special attention in the article is paid to multi-band and wide-band rectennas. It is noted that such rectennas can store more energy and produce higher output DC power compared to narrowband rectennas. The design features of low-power rectifiers for rectennas of EM power harvesting systems from the surrounding space are considered. It was determined that the energy characteristics of rectannas are characterized by numerous factors and there are three approaches to their improvement. The first approach is to improve the parameters of individual rectifier elements, the second is to optimize the parameters of individual rectenna elements and the third is to optimize the entire rectenna as a whole.

“…Passive circuit techniques typically have a very low power harvesting capability deficiency [33][34][35]. Therefore, in order to increase the harvested energy, the active technique and its components, including MOSFET, thyristor, and transistor, have been recommended, proposed, and depending on the type, the energy harvesting interface circuit has been suggested [36][37].…”

In piezoelectric energy harvesting systems, energy harvesting circuits are the interface between piezoelectric devices and electrical loads. The conventional view of this interface is based on the concept of impedance matching. In fact, in the power supply circuit can also apply as an electrical boundary conditions, such as voltage and charge, to piezoelectric devices for each energy conversion cycle. The major drawback of piezoelectric power harvesting have low-power relationships in systems within (in the range of μW to mW), then system also have significantly reduced any potential losses in circuits that make up the EH system, whereas other condition into careful selection of circuits and components can enhanced the energy harvesting performance and electricity consumption. In the study of energy harvesting systems, it is an energy harvesting system approach that using active and passive electronic circuit to control voltage and or charge on piezoelectric devices as proposed and review to mechanical inputs for optimized energy conversion. Several factors in the practical limitation of active and passive energy consumption, due to device limitations and the power efficiency of electronic circuits, will be introduced and have played an important role into to enhance optimum and increase efficiency of energy harvesting system.

“…Результаты, приведенные на рис. 6, показывают, что КПД выпрямления можно повысить за счет выбора типа излучающей структуры ректенны, а также за счет применения эффективных схем выпрямления [11,12]. Следует отметить, что в зависимости от конструкции подвески может возникнуть ситуация, когда необходимо устанавливать ректенны на выпуклые поверхности, что приведет к необходимости анализа излучающих структур ректенн, реализованных на подложках, повторяющих форму деталей (объектов), на которых они установлены.…”
