Smart Energy Harvesting System for IoT & Cyber Physical Devices

The modern IoT & cyber-physical systems often rely on wireless or independent energy sources that do not need battery change or manual recharging. Recharging of such systems is often delivered by rectifying antennas. In this paper we propose an energy harvesting system for IEEE 802.11 standard that can work within Wi-Fi frequency range (2412 MHz-2472 MHz and 5160-5825 MHz). The proposed system is based on phased patch-antennas with focusing and scanning of electron beam. The use of such a system increases the gain, power characteristics and, consequently, the productivity of a smart energy harvester compared to energy harvesting systems with a single antenna.
