MUMBAI, India, June 6 -- Intellectual Property India has published a patent application (202311082230 A) filed by GLA University, Mathura, Uttar Pradesh, on Nov. 30, 2023, for 'an implemented radio frequency energy harvester (rfeh) system.'
Inventor(s) include Dr. Abhay Chaturvedi; Dr. Gaurav Kumar Sharma; and Karishma Yadav.
The application for the patent was published on June 6, under issue no. 23/2025.
According to the abstract released by the Intellectual Property India: "The present invention relates to an implemented Radio Frequency Energy Harvester (RFEH) system designed for efficient energy harvesting from radio frequency (RF) sources. The system comprising an antenna configured to receive electromagnetic signals. The received RF energy is then directed to a power harvester, electrically coupled to the antenna, which converts the energy into a direct current (DC) voltage, resulting in the generation of a first power associated with the DC voltage. To ensure stability, a regulator is integrated into the system to control and regulate the power associated with the DC voltage, producing a consistent and regulated power output. The system further incorporates a rectifier circuit, connected to the antenna, for the conversion of RF power into direct current (DC) energy. Energy storage is facilitated through a pair of capacitors (C11 and C12) configured with 1uF values, serving to store received energy, and connected to a larger power storage component with 5000uF values for storing rectified energy. The rectification process is achieved through the use of a plurality of 1N418 diodes strategically connected within the rectifier circuit. This comprehensive RFEH system demonstrates a sophisticated approach to harnessing and storing RF energy for various applications."
