Summary:
Recently, the availability of free RF energy has increased due to advent of wireless communications and broadcasting systems. RF energy harvesting is the process of extracting small amounts of energy from the ambient environment. This energy can be used to power either portable electronic devices, such as wireless sensing nodes, mobile phones and medical devices, or to charge electrical storage devices (rechargeable battery or capacitor), which can be used at different time intervals for power applications. RF energy harvesting technology is strongly depended on the RF-DC rectifier circuit in the wireless power transmission. The RF-DC rectifier for converting microwave power to DC power has attracted considerable attention in the development of the wireless power transmission. The application of this technology can be used in low power mobile devices, such as radio-frequency identification (RFID) and Zigbee. In this paper, we show the power conversion efficiency of developed RF-DC rectifier circuit for RF energy harvesting.
