Design of impedance matching circuits for RF energy harvesting systems

This paper presents a systematic design methodology for impedance matching circuits of an RF energy harvester to maximize the harvested energy for a range of input power levels with known distribution. Design of input matching networks for RF rectifier differs from those for traditional RF circuits such as low-noise amplifier because the transistors in the RF rectifiers operate in different reg...

Design 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.

Development of RF Energy Harvesting and Charging Circuits for Low Power Mobile Devices

The electrical power generated by RF energy harvesting techniques is small, depending on techniques it is enough to drive low power consumption devices. Therefore, it is possible to increase the battery life and to reduce the environmental pollution. In this paper, we focus on the RF energy harvesting and design the rectenna with a 4×4 patch antenna of 2.13 GHz for low power mobile devices. The...

Design and Implementation of Microstrip Antenna for RF Energy Harvesting

This paper describes the antenna design for RF power harvesting system. The design goes through three phases designing of antenna, matching network and rectifier. A dual band Microstrip antenna suspended above ground plane is designed to operate in GSM 1.8 and ISM 2.4 GHz bands. The antenna incorporates the capacitive feed strip which is fed by coaxial probe technique where the inductive impeda...
