    This paper discusses key factors in the design of RF energy harvesters that have a significant impact on overall efficiency, and in particular the critical role of selecting a high-quality factor inductor in the matching network. The proposed rectenna is composed of an L-matching network and a half-wave rectifier, and the target frequency is 868 MHz. First, a circuit analysis is presented to ...
    • A Versatile RF Energy Harvester for IoT Sensors in 5G Network With ...

      The widespread adoption of fifth-generation (5G) wireless technology in Internet of Things (IoT) networks introduces a battery replacement challenge for countless IoT sensors. To address this issue, researchers are exploring energy harvesting techniques that involve extracting energy from radio frequency (RF) signals. The dense deployment of antennas in 5G networks, compared to prior ...

    The targeted input signal to the RF chain is within the range of input power from −10 dBm to 2 dBm at 2.4 GHz. Although GSM900 is reported to have a good ambient density [15], the target RF energy band at 2.4 GHz is more suitable for on-chip integration since it will result in a smaller inductor value with higher quality factor. Accordingly ...

    Ambient RF energy harvesting is one of the very useful energy sources for IoT devices, but, when the power of available ambient RF signals is low, the output DC voltage of the RF rectifier is lower than the voltage required by the system, making it difficult to use it as a power source [24,25,26]. Therefore, the proposed RF energy harvesting ...

    RF energy-harvesting systems have garnered significant attention because of the consistent and ambient presence of RF energy from Wi-Fi, cellular, and radio stations. The key elements of an RF energy-harvesting system is a rectenna, a voltage multiplier, and a storage/controlling unit, as Fig. 7 shows.

    Regarding RFT, only the case of ambient RF energy harvesting has been considered. Wireless power transfer solutions have not been mentioned. Sleebi et al. propose in the review entitled "RF Energy Harvesting: An Overview and Design Issues". An emphasis is placed only on the design considerations of the receiving antenna and those of the RF ...

    An example illustration of an IoT node with RF-energy harvesting (RF-EH) unit is presented in Fig. 2. These energy harvesting schemes aim to ensure energy neutral operations (ENO) [23] across the IoT network. However, the non-perpetual nature of the above-mentioned energy harvesting sources results in inadequate energy harvesting, which is ...

    RF Energy Harvesting (RFEH) [1,2,3,4,5,6,7] is gaining interest due to its continuous availability in urban environments compared to other renewable energy sources like solar, thermal, and piezo EH. In an indoor environment, the RF signal is concentrated, and in the outdoor environment the weather, season, and illumination have less impact ...
