This paper proposes a compact Thévenin model for a rectenna. This model is then applied to design a high-efficiency radio frequency harvester with a maximum power point tracker (MPPT). The rectenna under study consists of an L-matching network and a half-wave rectifier. The derived model is simpler and more compact than those suggested so far in the literature and includes explicit expressions of the Thévenin voltage (Voc) and resistance and of the power efficiency related with the parameters of the rectenna. The rectenna was implemented and characterized from −30 to −10 dBm at 808 MHz. Experimental results agree with the proposed model, showing a linear current–voltage relationship as well as a maximum efficiency at Voc/2, in particular 60% at −10 dBm, which is a remarkable value. An MPPT was also used at the rectenna output in order to automatically work at the maximum efficiency point, with an overall efficiency near 50% at −10 dBm. Further tests were performed using a nearby tra...

This report focuses on designing, measuring and testing of an antenna combined with a rectifying circuit (RECTENNA) which is connected to a LTC 3108 IC DC-to-DC converter for further amplification of transmitted low power density at a microwave frequency of 2.45 GHz.
This rectenna is used to harvest and amplify the electric energy from the RF signal transmitter and the surroundings which radiated at ISM band centred in 2.45 GHz, on the thesis methods of simulating the rectenna is analysed with harmonic balance using Agilent Advanced Design Software (ADS) and Multisim. This antenna is later fabricated and measured; the S-parameters are then matched and combined with the LTC 3108 IC.
This project is inspired for the practical use of wireless power transmission, low-power applications and RF recycling of the energy consumed in our environment which is wasted and not fully utilized.

— In this paper, we propose a compact and highly efficient Rectenna design (rectifying antenna), operating on ISM band with the centre frequency of 2.4 GHz. A RF to DC conversion through Schottky diode (HSMS2860) is used to generate the dc voltage to operate a battery-less IoT Sensor for RF power harvesting using the designed Rectenna. We have achieved more than 80% efficiency through Advanced Design System (ADS-2016) simulation software at different power densities. Further a rectenna circuit is designed using RF to DC Schottky detector diode and a microstrip patch antenna. The rectenna circuit design is simulated through ADS 2016 simulation software. The Battery less sensor requires 2V-2.5V dc voltage to perform an optimum performance. As per simulation and theoretical/practical modeling we have achieved more than 80% efficiency at single Schottky diode and its operating from 915 MHz to 5.8 GHz. Rectenna operates at lower power densities start from 0.4uW/cm. The proposed rectenna design is a possible candidate to be used as sensors/devices at frequency of 2.4GHz with current technologies e.g. ZigBee, Wi-Fi, BLE etc and future probable application could be long range radio sensor using the latest new generation LoRa technology its line of sight range between 10km-20km.

As we know that Sun is the great source of energy on the earth & we can't even imagine the life of any living organisms on the earth .Energy can be produced in three modes 1.Induction(In which two bodies are not connected together but even there is requirement of medium ) 2. Conduction (In which bodies are in contact with each other & it also requires medium) 3.Radiation(In which there is no contact of bodies but energy transmitted in form of photons). Solar energy is radiant light & heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating ,photovoltaic, solar thermal energy .It is an important source of renewable energy and its technologies are broadly characterized as either passive solar or active solar on how they capture and distribute solar energy or convert it into solar power. Wireless Power transmission (WPT) is a useful and convenient technology that can be employed to collect solar energy and concentrate on earth surface without the need for a wire connection called a solar power satellites (SPS). This paper provides an analysis of wireless power transfer with an assessment of its practical applicability in terms of power range and efficiency. In this paper, various technologies available so far for wireless transmission of electricity and the need for a Wireless Energy Transmission will be discussed to find its possibility in actual practices. Also, their advantages, disadvantages and economical consideration will also be presented. This paper concentrates mainly on (i) The most popular concept known as Tesla Theory, (ii) The microwave power transmission(MPT) called Solar power satellite, and (iii) The highly efficient fibre lasers for wireless power transmission. Many concepts, research papers, and patents are available on wireless transmission of electricity but the commercial technologies are yet to be materialized. This paper will also discuss the possible ways to get useful and practical results out of all researches carried out so far elsewhere. The output microwave power ranges from 50W to 200W at 2.45GHz. A coaxial cable is to connect the output of the microwave source to a coax-to-waveguide adapter. This adapter is connected to a waveguide ferrite circulator which protects the microwave source from reflected power. The circulator is connected to a tuning waveguide section to match the waveguide impedance to the antenna input impedance.

This article is dedicated to the design of rectifying antenna for wireless energy transfer at 2.45 GHz in the special case of low input power (typically <;-10 dBm). As the rectifiers present an important non-linear behavior with such power levels, specific design guidelines must be respected in order to optimize the structure. Different rectifying circuits have been studied and their performances have been evaluated through the definition of a Figure of Merit. The effects of the antenna impedance have also been investigated to improve the performances. Two test-circuits have been manufactured and measured to validate the simulation results and to confirm the interest of a global design approach with such rectifying structures.

In the recent days, the usage of wireless communication plays vital role in this electronic world. The utilization of RF signals from sources is more. These RF signals can be utilized and converted as usable DC power by using rectenna. This paper presents design of rectenna for 900MHz (GSM band) frequency. The received signal is matched with voltage multiplier circuit for RF to DC conversion and high voltage output. Villard voltage multiplier circuit is used. The designed antenna radiates 3.576dB power at 900MHz.The rectification has single stage voltage multiplier gives 2.688V with the maximum input value of 181mV and minimum input value of 1.456mV. By using single stage voltage multiplier, the output voltage is 4.139V with maximum input value of 181mV, minimum input value of 7.99mV Advanced Design System (ADS 2008) is used for simulation.

In this paper, design procedure and characteristics of an RF energy harvesting circuit based on single-stage voltage multiplier rectifier have been discussed and analyzed. This circuit is capable to recycle RF energy at 2.45 GHz, and by connecting to a 2.45 GHz antenna, it is possible to form a complete rectenna device. The values of output dc voltage and power according to the received RF power have been measured and the best value of load resistance to harvest maximum output dc power has been selected by simulation.

This work presents harmonic harvester Rectenna integrated power management circuitry for improving RF-DC power conversion efficiency. The circuitry is developed for battery charging or energy storage application; resistance emulation method is used to realize a matching load resistance at output terminals. The proposed technique is useful for harvesting near maximum output power from the dual rectifiers (fundamental and harmonics) independently. Also, it delivers the combined maximal power to the energy storage cell. The power management module based on dual input buck-boost converter with simple open loop control is utilized.

This paper presents the development of a circuit modeling for paralleled series loaded resonant (SLR) converter used in an experimental power supply to drive high voltage and high frequency medical equipment. The circuit model for each individual converter is first described. Once the complete model of an individual converter is achieved, the model is then extended to include the parallel connection. To verify the validity of model, the design of paralleled SLR using the model is explained. The component values obtained are then being used in Pspice simulations to further prove the validity of the model.

We propose a new method of combining antennas and solar cells to collect and transmit optical and radio frequency signals respectively. In this work, we determined the electrical power collected, it can be used for the polarization of a diode or a low-noise amplifier in a receiver block thus simulation results provides a gain of 6.74 dBi at 2.9 GHz with an effective return loss of-33.62 dB and radiated power of 7.08 mW. These good results make it possible to use the antenna particularly in point-to-point communication systems. A three topologies of rectifying circuits are proposed in the present work.

Slot antenna is designed with microstrip feed line for Wireless Local Area Network (WLAN) applications. The first patch is designed as a rectangular shape and the other is designed as an inverted L shape. The antenna is printed on a FR4 substrate with a thickness of 0.8mm and relative permittivity of 4.6.The resulting antenna is found to have a compact size of 22.75x22mm 2. It offers dual band characteristics with-10dB return loss and it radiates in omnidirectional pattern. The antenna receives RF signals which are converted into DC power by connecting it through the matching circuit, rectifier and voltage multiplier. Matching circuit is needed for matching the impedance of the antenna and the impedance of the rectifier. Rectifier uses schottky diode (HSMS 2850) which has high switching speed and low forward voltage convert the input RF signal received by the antenna into suitable DC supply voltage. The produced DC voltage can be doubled by using voltage doubler. The output power from the voltage doubler is given to low power devices for charging. These designs are simulated by using ADS 2011 (Advanced Designs System) software.

ABSTRACT This paper presents an analysis of optimum rectifier circuits for wireless energy harvesting in deep brain stimulation (DBS) devices. Since DBS demands compact and low power consumption devices, small, high conversion efficient, and high output voltage rectifiers need to be developed. The investigation that is presented in this paper is analytical and simulated based. Analysis on a variety of circuit configurations brings more evidence to improve the performance of rectifiers. Analytical parameters influencing the output DC voltage and the efficiency of the rectifiers are described. The operating frequency of the 915 MHz industrial, scientific and medical (ISM) radio band is used in this study. The maximum conversion efficiency of the LC matched half wave rectifier, the Greinacher voltage doubler, the Delon doubler, and the 2-stage voltage multiplier is obtained as 56.34%, 74.45%, 71.48%, and 31.44%, respectively, at the 30 dBm input power level. The corresponding maximum output DC voltages are 6.27 V, 16.83 V, 13.36 V, and 9.20 V. Thus the Greinacher voltage doubler is deemed as the best configuration according to the conversion efficiency and the output voltage measurements.

We derive thermodynamically an expression for the theoretical open circuit voltage of a rectenna device that converts high frequency ac radiation into dc power output. In addition, we obtain the conversion efficiency of an electron emission rectenna, which consists of a nano-antenna collector and a geometrically asymmetric rectifying MVM tunnel junction. This quantity plays an analogous role to the fill factor for conventional n–p semiconducting PV devices in limiting the overall efficiency. Thus, in effect, we develop a theory analogous to the Shockley–Queisser theory or limit (SHQL) for rectennas. The predicted limitations on the efficiency of the electron emission device, as in the case of the SHQL for n–p junction devices, are useful for guiding the development of practical devices based on rectennas[1]. These are useful benchmarks for evaluating different electron emission-based schemes for energy conversion.
