Ambient RF Energy Harvesting Technology and its Applications
— This paper is focused on equipping wireless devices (including sensors) with novel, high efficiency circuitry to harvest and convert ambient RF power to direct current (dc). Key components of this technology are (a) miniaturized antenna and (b) high efficiency rectifying circuit. The first is responsible for capturing the RF waves, and the latter coverts the RF energy to dc. A major challenge...
متن کاملDesign and Implementation of Ambient RF Energy Harvesting Circuits
This paper presents design strategies and measurements of two RF energy harvesting circuits working at UHF frequencies (around 480 MHz). Ambient RF sources are considered so for the circuit designs low power levels have been assumed. The circuits were implemented and the RF/DC conversion efficiency was measured. Index Terms – Matching network, RF energy harvesting, schottky diode, voltage doubler.
متن کاملAnalysis of K-Tier Uplink Cellular Networks With Ambient RF Energy Harvesting
We use stochastic geometry to develop a comprehensive modeling framework for K-tier uplink cellular networks with RF energy harvesting from the concurrent cellular transmissions. In the considered system model, channel inversion power control is used and cellular users are equipped with energy storage units. We also use tools from queueing theory, namely, Markov chain analysis, to model the lev...
متن کاملVivaldi Antenna for RF Energy Harvesting
Energy harvesting is a future technology for capturing ambient energy from the environment to be recycled to feed low-power devices. A planar antipodal Vivaldi antenna is presented for gathering energy from GSM, WLAN, UMTS and related applications. The designed antenna has the potential to be used in energy harvesting systems. Moreover, the antenna is suitable for UWB applications, because it o...
متن کاملRF Energy Harvesting System And Rectennas
Recent advances in ultra-low power wireless communications and energy-harvesting technologies have made self-sustainable devices feasible. Typically, the major concern for these devices is battery life and replacement. Applying energy harvesting techniques to these devices can significantly extend battery life and sometimes even eliminate the need for a battery. This technique is widely applica...
