“…In that case a diode with high is, and C ) may be preferred. However broadband matched RF harvesters may have low efficiency (output DC power/input RF power) and low voltage sensitivity as a tradeoff; as was shown in [6]. The effect of Is, Rs and Cj on the parallel reactive impedance of the Schottky diode is shown in Fig.…”

This work presents the effect of parasitic components on the performance of wireless RF energy h�rvesters. Since ambient RF power density is low, only optimal wireless RF energy harvesters will be able to power remote microwatt sensors. By knowing the effect of each parasitic component on the performance of wireless RF harvesters, components may be realized or selected that increases the overall efficacy of the harvester. The analytical and experimental investigation of the component parastics on the harvester output performance is compared at various operating frequencies; both at HF and UHF.

“…As previously discussed, a matching network was not used. The estimation of the power gathered from the antenna system and being available to the resistor R L , in case of one or four dipoles with the DNG slab or in free space, was made considering that each dipole is connected to its own rectifier and using (10). An alternative solution would be the combination of the signals of two dipoles, for example, the signal of dipole 1 with that of dipole 2 and the signals of dipoles 3 and 4 and then the leading of them to a rectifier.…”

“…The single drawback of the RF energy could be that, among the above mentioned resources, it is the one with the lowest power level in the ambient, exhibiting power density about 0.2 nW/cm 2 -1 μW/cm 2 . The main units of an RF power collective scheme are (a) the element that captures efficiently the ambient energy, being, in practice, an antenna, (b) a rectifying circuit that converts the gathered AC electromagnetic energy to direct current (DC) energy, and (c) a device that stores the DC energy. A great variety of schemes which include the first two grades of a harvesting system have been proposed in the literature, and the majority of them introduce antennas of printed type incorporated with rectifying units [5][6][7][8][9][10][11][12]. Moreover, effective solutions with metamaterial or fractal concept-inspired antennas [13][14][15], with dielectric resonators [16,17] and metasurface closed ring arrays [18], have also been presented.…”

The concept of harvesting the ambient electromagnetic radiation energy, coming from public telecommunication wireless networks, has been recently subject of extensive research. Techniques proposed for this target use mainly antennas, as the grade gathering the radiation power. In this work, a method introducing the usage of specific dielectric structures with artificially negative electric permittivity and magnetic permeability (double negative media or DNG) in combination with wire dipole antenna sensors is proposed as an RF harvesting system. Theoretical study of the synthesized DNG medium’s performance and the distribution of the electromagnetic field in its interior is made, with the intention of finding the areas of maximum electric field intensity at which the antenna sensors would be positioned for maximum power scavenging. The received numerical results show that the synthesized schemes are capable of enhancing the energy gathering ability. Compared to the same antenna sensors positioned in free space, they ensure higher input voltage to the rectifier and also an increase of the available power about 10 dB. Moreover, they exhibit this performance for every direction of arrival of the incoming waves. The hybrid schemes DNG dipole antenna were designed for the Universal Mobile Telecommunication System (UMTS) frequency band, but the method is general and would be applied to any other frequency band and also with other antenna types.

“…Hence, this method will be useful for long‐duration measurement applications that require only low‐power consumption. In Nimo et al, the efficiency of wireless EM harvester has been enhanced by a broadband antenna for the frequency range of 600 MHz to 2 GHz. These antennas are used to enhance the efficiency.…”

Renewable energy sources from the earth constitute another option apart from the available ones for wellspring of energy for economizing on cost of power supply. The energy obtained from ambient sources is called energy harvesting. Energy-harvesting low-power systems have acquired a remarkable consideration as a viable hotspot for expanding both energy efficiency and spectral efficiency. Radio frequency (RF) energy harvesting from ambient source is a promising technique for fulfilling the irreplaceable power prerequisites for powering the low-power devices. Hence, it requires the development of an antenna for harvesting RF energy. In this paper, a coplanar waveguide (CPW) antenna has been designed and fabricated using FR4 lossy substrate. This CPW antenna covers frequency bands from the most important RF patrons (GSM 900, GSM 1800, 3G, and Wi-Fi) within the frequency range from (0.58 to 3 GHz) with a percentage fractional bandwidth of 116% with the center frequency of 1.65 GHz. The fabricated antenna then has been experimentally validated at SSN College of Engineering campus. The effects on the RF power density level for CPW antenna are examined by statistical approach known as Taguchi method. The L9 and L8 orthogonal arrays and analysis of variance are implemented to analyze the execution qualities. The CPW antenna control factors are distance, time, and number of receivers. Then, statistical test (P) are used to determine the significant factors on RF power density. KEYWORDSANOVA, CPW antenna, RF energy harvesting, spectral survey, Taguchi orthogonal array | INTRODUCTIONThe enormous growth in communication networks has triggered persistent expansion of the need for energy supply, leading to a battery exhaustion issue for wireless communication devices. 1 Research work has been conducted recently to increase energy from ambient sources, which is an alternate option for maintaining a sustainable energy supply instead of rechargeable or replaceable batteries. 2 Energy harvesting has been proposed for accomplishing this and ensuring unlimited energy supply to electronic systems and saving energy consumption. 3,4 Hence, energy harvesting grasps energy from the ambient environment and stores them for future use. There are different types of energy harvesting such as thermal, solar, and radio frequency (RF). Energy harvesting from electromagnetic (EM) radiation has huge consideration because of wireless communications networks. 5 Electromagnetic radiations from the far-field applications have emerged in the form of radio frequency and can be collected by aerial, which converts the radio waves into electric power using rectifier circuits. 6 This paper envisages the usage of harvesting arising from the availability of frequency bands such as Wi-Fi routers, cell phones, and laptops. Cognitive radio can be powered from RF ambient sources, which improve the spectrum efficiency and energy efficiency. 6 Use of the RF signal and the distance between an RF energy source can help harvesting RF energy. First, the purpose of the ...
