Energy harvesting from ambient RF sources
2012 IEEE MTT-S International Microwave Workshop Series on Innovative Wireless Power Transmission: Technologies, Systems, and Applications, 2012This paper presents a feasibility study of energy harvesting from ambient radio frequency (RF) sources. A preliminary assessment of the ambient RF energy was carried out by calculation of power spectrum density and measurement of received power in a common suburban area.

RF Energy Harvesting Circuits and Designs
2021The RF energy harvesting, a new booming research area during last decade for generating a small amount of electrical power, and its application in low-power electronics. A novel approach of Schottky diode-based Villard voltage multiplier circuit for energy harvesting application is proposed.

Waveform-aware ambient RF energy harvesting
2014 IEEE International Conference on RFID (IEEE RFID), 2014In this paper we suggest a new class of RF energy harvesters, which we call “waveform aware harvesters”. In contrast to traditional rectenna designs, which are usually designed for high efficiency with continuous wave (CW) signals, waveform aware harvesters are RF to DC converters which are optimized for their performance with non-CW signals.

Textile-Integrated Rf Energy Harvester
2017In the paper, we present a dual-band wearable rectenna operating in 900 MHz GSM band and 2.45 GHz ISM band. The rectenna was designed as a multilayer structure to reduce size while having a large enough aperture with a reasonable gain. The antenna was connected to the rectifier by a current probe via a textile substrate.

Sensitive ambient RF Energy harvesting
Rectification of microwave signals to generate DC (Direct Current) power has become the subject of research since the 1950’s. Radio Frequency (RF) energy harvesting has experienced a rapid development in recent years due to the increasing number of RF transmitter sources producing an abundant ambient microwave energy waste.Furthermore, the development ...openaire +1 more source
DUAL BAND RF ENERGY HARVESTING SYSTEM
We present a compact dual-band RF energy-harvesting system integrating antenna, matching and rectification techniques from recent studies, enhanced with intelligent monitoring and power management. The proposed architecture operates across two major RF bands—UHF (≈0.9/1.8 GHz) and ISM (2.45/5.8 GHz)—using a dual- resonant antenna and adaptive Pi/T ...Dr. Malini S, Meghamala s, Nived madhu
