Analysis of Passive RF-DC Power Rectification and Harvesting Wireless RF Energy for Micro-watt Sensors

Radio Frequency Energy Harvesting Sources

“…A system efficiency of 32% was realised in the frequency range 1.9 -2.3 GHz. In 2015, Nimo [53] designed a dual band antenna with a passive dual band rectifier that produced RF power in the order of -27dBm to -50 dBm which managed to power a thermoshygrometer at a distance of 110m from a GSM 900 base transceiver. In 2016, Uzun [52] made a rectenna that consisted of a two -stage voltage multiplier and an Ltype impedance matching circuit for powering of low power sensors from a GSM 900 cell tower.…”

On-Site and External Energy Harvesting in Underground Wireless

“…Rectennas have been used for transmission of microwave power [132] and satellite power to analyze the performance of a rectenna array [133]. It consists of an antenna for capturing waves in the from of AC current, and a rectifying circuit to perform AC-DC conversion [134,135]. Multiple antenna types and rectifying circuits have been used in order to design an efficient antenna.…”

Design of efficient rectifier using IDC and harmonic rejection filter in GSM/CDMA band for RF energy harvesting

“…(b)] parameters of the diode are given by the breakdown voltage V B = 7 V and the built‐in turn on voltage V F = 0.3 V. The junction resistance R j of the diode is variable depending on operating conditions. The loss in diode circuit depends upon value of series resistance R s while the switching speed of diode depends upon C j . Therefore, diodes with lower junction capacitance and series resistance are preferable.…”
