In recent years, with the rapid developments in the field of technology and the development of wireless communication systems; led to a noticeable increase in the number of portable, rechargeable and low-power devices. These electronic devices have become a necessity even in our simplest works, due to the increase in their number and variety; It is desired that the energy needs can be met continuously and quickly at a low cost. Batteries, which are non-renewable generators, provide the energy required for such low-power devices in the world. The increase in the tendency towards non-renewable energy sources leads to negative environmental and economic consequences. Therefore, it becomes important to turn to renewable energy sources and to work on it. Energy harvesting systems, which are an innovative energy source, are the best potential alternatives to collect the energy needed by the mentioned low-power devices. With the increase of different frequency bands such as GSM 900, GSM 1800, UMTS, 3G, Wi-Fi, Wi-Max and LTE, RF energy harvesting is becoming quite common. In this paper, a printed multiband microstrip patch antenna is presented. Antenna design covers numerically calculated frequencies of 1.6dBi at 2.4GHz, 3.95dBi at 5.2GHz, gain values, and frequencies often used for electronic device communication such as Wi-Fi 2.4GHz and WiMAX. The proposed antenna design has allowable gain values to be used for RF energy harvesting applications.

In this research work, a hexagonal shape microstrip patch antenna has been introduced to work for two 5G frequency bands, n78 (3300–3800 MHz) and n77 (3300–4200 MHz) for radio frequency (RF) energy harvesting applications. The resonant frequency for the 5G n78 and 5G n77 bands is 3.55 GHz and 3.75 GHz, respectively. To improve the characteristics of the antenna at the anticipated resonant frequency, a hexagonal shape slot is embedded in the ground plane. A working bandwidth of 2.0 GHz (2.80–4.88 GHz) cantered at 3.7 GHz (5G n77), is achieved. The proposed antenna exhibits a bidirectional radiation pattern with a peak gain of 3.74 dBi at 3.7 GHz. The height of the FR4 substrate is set constant at 1.6 mm. A comparative study has been performed on different substrate materials to know the effect of dielectric properties on the proposed hexagonal-shaped microstrip patch antenna (HSMPA).

Advancement of modern society is required to address the power issue. Previously the energy harvesting techniques were taken into consideration without knowing their probability to work in another setting. To capture energy from radio transmissions, a microstrip antenna is designed in the paper. Gathering of energy from nearby sources for energy harvesting is an alternate strategy for low-energy use. A continuous supply for energy harvesting from radio frequency signal has similar effect as the ones from known sources like wind and solar. The arriving low-amplitude signals are demanding larger number of antennas alternatively for greatest amount of required energy. Microstrip patch antenna is in use because of its low profile, simplicity of configuration, and low rate of consumption to reduce the energy resources. The simulations on CST software and fabrication are performed to increase the power generated to charge a greater number of low-power devices using Radio Frequency Energy Harvesting (RFEH) for the ISM frequency band of 2.46 GHz. The microstrip patch antenna provides a result having return loss coefficient of 26.42 dB, Voltage standing wave ratio (VSWR) of 1.1, and a directivity of 6.14 dBi at ISM frequency band with operating frequency of 2.46 GHz. An EM signal of 1.4v source voltage is achieved, which after rectification gives an output voltage of 3.5 V. Additionally, the setup in conjunction with the suggested antenna design offers the highest level of energy efficiency. The achieved outcomes are effective and can be used to resolve some of the power problems faced by the technical world.

To power dedicated ultra-low-power Internet of Things (IoT) devices, high-voltage electric power must be converted to low voltage, which causes losses. Radio Frequency (RF) energy harvesting allows for scavenging ultra-low RF power from nearby RF sources. This paper proposes a single-band RF Energy Harvesting System (RFEHS) for the self-sustainable IoT application. The proposed Square Microstrip Patch Antenna (SMPA) is designed, simulated, and verified using Mentor Graphics software simulations and Computer Simulation Technology Microwave Studio (CST MWS) 3D electromagnetic simulator. For the design and simulation of the rectenna (Antenna + Rectifier), Advance Design System (ADS) is used. The SMPA is fabricated on Rogers RT5880 substrate material having a dielectric constant of 2.2 and a substrate thickness of 2.5 mm. The SMPA peak gain and directivity of 6.81 dBi and 7.24 dBi, respectively, are recorded. The proposed SMPA has an approximately omnidirectional radiation pattern at 2.45 GHz. The SMPA is tested on Vector Network Analyzer (VNA) to validate simulated CST MWS Mentor Graphics results. A single-stage voltage multiplier circuit has been analyzed and discussed using vendor-defined (Murata) library components. The rectenna has a maximum RF to DC conversion efficiency of 65.17% and a DC output voltage of 3.4 V at 10 dBm RF input power and load resistance, R= 3 kΩ. A Transmission Line (TL) equivalent model is derived for the proposed SMPA.

In this study, we developed an analytical model of slot-loaded rectangular microstrip patch antennas based on the simulation results by varying slot parameters. The dominant resonant frequency predicted by such a model is in strong agreement with the experimental results measured at several locations of slot-loaded rectangular microstrip patch antennas. The model enables a reliable and quick computation of the resonant frequency, which generally follows a harmonic behavior that nearly resembles the resonant frequency of a microstrip antenna without a slot, which can be related to a small change in the impedance caused by the slot position. Results showed a good agreement between simulations and measurements for all the slot positions. Mathematical analytic functions to describe the changes in specific characteristic parameters of the slot-loaded rectangular microstrip patch antennas are also included.

The rectenna as a device, is critical for achieving long-distance wireless power transfer. The centrality of this study is focused on adding to the collective knowledge of the subject matter, by providing a new perspective in terms of an alternative design for the antenna component of the rectenna. Essentially, this study features a novel “3-point star” design which was simulated in comparison with the conventional square microstrip patch antenna design. Both designs (i.e., operating at the Wi-Fi band 2.4 GHz), were assessed in terms of simulated performance parameters: gain, directivity, return loss, radiation pattern, and efficiency. From the simulation results, the proposed “3-point star” design, though slightly less efficient exhibited improved performance over the conventional square patch alternative, in terms of gain, directivity, and return loss. For the rectifying component, a greinacher voltage-doubler (with two HSMS2820 diodes), was designed separately and simulated over a range of input power levels (10dBm—34dBm), for 220-Ω, 380-Ω and 810-Ω load resistances, respectively. A maximum conversion efficiency of 88.02% was achieved at 28dBm for an 810 Ω load resistance. All design simulations were executed using Advanced Design System (ADS) software.

Purpose On average, a medium-sized satellite consist of almost 500 sensors where powering these sensors in space in such an unreachable environment is critical. Backing this, a compact energy harvester for powering up distant sensors is discussed here is the purpose of this paper. This is in line with the geostationary satellite-powered using the available electromagnetic energy on the satellite panels in space. Design/methodology/approach The designed rectenna makes use of a compact wideband receiving antenna operating at the targeted frequency band from 8 to 18 GHz. It also consists of a simple dual diode rectifier topology with a matching circuit, bandpass filter and a resistive load to convert the received radio frequency energy into usable direct current (DC) voltage. Findings The rectenna measurement is performed using three different configuration setups. This shows that a maximum DC voltage of 1.8 V and 5-10 mV is harvested from rectifier and rectenna (includes antenna and rectifier) when 20 dBm power is transmitted from the transmitting antenna operating at X and Ku band. This makes the rectenna feasible to power wireless sensors in a structural health monitoring system. Originality/value The measurements are performed by considering a real-time environment in space in terms of the distance between the transmitting and receiving antenna, which depends on the far-field of the transmitting antenna in a satellite.

span>Radio Frequency (RF) harvesting seems to be catching up as an alternate energy source whereby RF energy is scavenged from ambient sources and converted into renewable energy in terms of DC power. This converted DC power is then utilized to power up devices that require a low start up power in which eliminates the need for battery replacement. In this paper, a novel RF energy harvesting prototype is presented which consists of two microstrip patch antennas operating on GSM (900MHz) and WIFI (2.4GHz) & WiMAX (2.3GHz) frequency bands with a bandwidth of 220MHz and 10.11MHz respectively to harvest RF signals from ambience. Two matching networks are presented as well to ensure efficient power transfer to load. Rectifiers are designed to transform the RF signals to DC power. The converted DC signals are then combined and fed to a power management circuit which charges a 4.2V NiMh battery and drives a load at a regulated output of 3V.</span

There is pressure caused by increasing electromagnetic radiation in our areas, for example, UHF, VHF, WIFI, and WiMAX bands. In this context, the concept of energy recycling plays an important role. It is expected that WiMax technology with different standards is going to come to market (IEEE 802.16d and IEEE 802.16e). There are many cases where it is desirable to acquire energy form many radiofrequency stations, to produce electricity and efficiently charge any electronic device through the RF-DC conversion circuit. In general terms, the system is divided into two parts: Harvesting microwave energy around us and the RF-to-DC conversion circuit. The purpose of this work is to harvest microwave energy from two bands of operating frequencies ((f01= 2.4GHz) and (f02= 3.84GHz)) using Dual-band slot-loaded pin-fed linear-polarised rectangular patch antenna. The efficiency of acquiring RF depends on the amount and types of antenna and the efficiency of the RF-DC conversion circuit. However, the microwave energy obtained from the nvironment is usually at the scale of milliwatts which is a serious problem that limits the popularity of the WiMax power harvest. This paper presents a novel rectenna for highly efficient WiMax power harvesting. We evaluate the possible application of microwave harvesting, to charge a battery of a sensor.

In this paper, we focus on ambient radio frequency energy available from commercial broadcasting stations in order to provide a system based on RF energy harvesting using a new design of receiving antenna. Several antenna designs have been proposed for use in RF energy harvesting systems, as a pertinent receiving antenna design is highly required since the antenna features can affect the amount of energy harvested. The proposed antenna is aimed at greatly increasing the energy harvesting efficiency over Wi-Fi bands: 2.45 GHz and 5 GHz. This provides a promising alternative energy source in order to power sensors located in harsh environments or remote places, where other energy sources are impracticable. The dual-band antenna can be easily integrated with RF energy harvesting system on the same circuit board. Simulations and measurements were carried out to evaluate the antenna performances and investigate the effects of different design parameters on the antenna performance. The receiving antenna meets the required bandwidth specification and provides peak gain of more than 4 dBi across the operating band.

This paper presents the design of a highly compact printed rectenna for ambient RF energy harvesting around 2.45 GHz. Its antenna structure comprises a rectangular patch with two etched U-shaped slots fed by a symmetric 50 Ω coplanar line. In spite of compact size, it has been directly integrated with a rectifying circuit on the same substrate only at the expense of a 15% frequency shift. The proposed rectenna overall dimension is only 24.9 × 8.6 × 1.6 mm3, the smallest so far reported with comparable performance, which can be easily integrated with any device for energizing low-power wireless sensor networks. It was fabricated and experimentally characterized, achieving a reasonable agreement with the expected simulated results. Measured results indicate that, at the resonant frequency, the antenna part of the proposed rectenna provides a good matching level (<−25 dB) and has a 0.8 dBi peak gain as well as nearly symmetrical radiation properties (in both E- and H-planes). The measured RF-to-DC conversion efficiency (DC output voltage) of the proposed rectenna at a low incident power of −20 dBm is about 20% (97 mV) with a load resistance of 4.7 kΩ. A demonstration experiment of a LED driven by the rectenna was also presented.
