Radio-Frequency (RF) Energy Transfer and Harvesting Techniques with Rectifier and Antenna

Abstract

Electromagnetic energy has an important role in power and energy industry. As the demand for power increases, need for alternate energy sources are essential. Radio frequency (RF) energy transfer and harvesting techniques becomes one of the solutions. Basic RF harvesting circuit consists of three elements. This can be achieved by using a rectenna combination of rectifier and antenna. The antenna is to receive RF signal and rectifier to convert RF to DC signal in between an impedance matching circuit. This converted power is used by certain low power devices. This study presents possible sources applications and design configuration and current scenarios.
