The rising demand across various applications has spurred growth in the energy harvesting, which is a novel means to generate energy and provide energy to low-power devices utilizing the available resources. The primary part of energy harvesting systems that convert RF energy to DC power from existing sources is known as a rectifier. The objective of this study is to create an innovative rectifying circuit designed for energy harvesting at 2.45 GHz. The primary aim is to enhance the output voltage compared to existing rectifier circuits such as the Dickson and Cockcroft-Walton configurations. The proposed rectifier circuit exhibits exceptional output threshold and maximum output voltage. Moreover, it achieves a significantly improved power conversion efficiency (PCE), with an enhancement of 43% for the Dickson rectifier and 47% for the Cockcroft-Walton rectifier. To develop and evaluate the suggested rectifier circuit, simulations are performed utilizing the Schottky diode HSMS 285C. The input power range considered for the simulations varies from -20 dBm to 35 dBm. To validate the simulation results, fabricated models for the three prominent topologies have been developed, and the simulation and measurement outcomes agree well, confirming the suitability of the proposed topology for harvesting RF Wi-Fi signals. Results demonstrate that the presented rectifier surpasses the operational attributes of the conventional the rectifying networks in relation to output voltage and PCE.

Radio frequency energy harvester is the conversion of ambient radio frequency electromagnetic waves into usable electrical energy, powering low-power devices without traditional power sources. In this paper, a novel RF energy harvester is proposed for 700 MHz frequency band. For the purpose of rectification, a Greinacher voltage rectifier cum multiplier is used in the circuit and Schottky Diode HSMS-2852 is used for implementing a rectifier. The LC impedance matching is implemented to improve the circuit performance of the harvester including conversion efficiency and output voltage. Simulation of the rectifier is done using the PathWave Advanced Design System (ADS) software. The rectifier shows the optimized performance at 5 kΩ load impedance. Simulation results show the highest efficiency of 33.1 % and an output voltage of 3.2 V with 8 dBm RF power at 700 MHz input frequency.

A voltage multiplier rectenna is a combination of a voltage multiplier rectifier and an antenna used for the conversion of AC to DC. It is an essential part of the system of RF energy harvesting. Conventional rectennas are characterized by low conversion efficiency. This study presents an analytical novel mode designed for RF energy harvesting systems to study the voltage and current output of rectifier stages for efficiency optimization. The design contains a voltage multiplier rectification circuit with seven stages. The Schottky diode HSMS 285-C was selected for the circuit modeling voltage multiplier circuit. Advanced Design System (ADS) simulation was used to validate the equations of the theoretical model solved with MATLAB code. The fabricated system was tested for an input power range of 10 μW to 100 mW; the maximum output power is 0.2577 mW with maximum efficiency of 29.85%.
