“…As a result, RF waves are emitted with low power levels in the space, which complies with the maximum output power levels' regulations [39]. RF is not limited by time, i.e., RF energy is available 24 h, seven days a week, during the whole year [40]. This feature promotes research to realize RF energy harvesting technology through the applications of WSNs [41,42], internet of things (IoT) [43,44], implantable devices and remote patient monitoring [45,46], and radio frequency identification (RFID) [47,48].…”

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.

“…Energy scavenging can provide a continuous power to feed WSNs for autonomous sensors [2]- [11]. Radio frequency (RF) wave is one of the renewable sources that is broadcasted for 24 hours per day through different sources such as routers, radar systems, radio transmission towers, and mobile base stations [12]. That is why RF energy harvesting is considered a viable solution.…”

Energy scavenging is a promising technique for micro-devices such as wireless sensor networks (WSNs). Radio frequency (RF) is considered a sustainable source that can be utilized and harvested due to its important features. The essential goal of this study was designing and investigating a wide input power range through a theoretical and simulation work for the 900 MHz frequency band with acceptable efficiency. In this work, we investigated both the low input power and the high input power range circuits; the two circuits were combined to achieve the goal of the wide input power range. L impedance matching elements were used to perform the desired matching between the power source and the circuit to reduce the reflected power resulted in enhanced RF-DC conversion efficiency. 60 % was the peak efficiency for the proposed design at 0 dBm with the output voltage of 16.56 V, and a generated current of 1.39 mA for the load of 12K. INDEX TERMS Conversion efficiency, input power level, rectifier topology, RF energy scavenging.
