Abstract
Radio frequency energy harvesting is one of the new renewable sources that faces some technical challenges, which limit its performance. This study presents two scenarios to enhance the harvested power. The first scenario introduces a quad-band voltage multiplier circuit with a single receiving antenna and four band-pass filters of elliptic type. In this scenario, four frequencies of the Global System for Mobile communications, Universal Mobile Telecommunications System, and Wireless Fidelity frequency bands have been considered for the study. The second scenario proposes a quad-band voltage multiplier circuit with four receiving antennas at the same frequency bands as the first scenario. High conversion efficiencies were achieved for the two scenarios. The proposed quad-band system developed a harvested power level, sufficient for powering up low power micro-devices with no need for an external power supply.
Highlights
Energy harvesting will become a promising technique in the future with tremendous scope instead of replacing small batteries in low-power electrical devices that overcomes the defects related to traditional batteries stated above
radio frequency (RF) energy that belongs to the electromagnetic waves are abundant in space since they are broadcast vastly in the urban ambient environment through RF/microwave frequency bands for instance, the Global System for Mobile communications (GSM 900, GSM 1800) bands [21,22], and Wireless Fidelity (Wi-Fi 2.45 GHz/5.8 GHz) [23,24] bands due to the current applications utilized by societies such as smart medical applications [25], intelligent environment monitoring [26], satellite communications [27,28], mobile telecom
The non-linearity of the Schottky diodes is due to the variation of the input powers or frequency
Summary
These defects include the demand for power maintenance, limited life span, requiring periodic replacements, and the processing of the battery wastes. All these are considered to be weak points for traditional batteries. Energy harvesting will become a promising technique in the future with tremendous scope instead of replacing small batteries in low-power electrical devices that overcomes the defects related to traditional batteries stated above.
