Fully-Integrated Energy Harvesting Mobile Antenna Based on GSM 1.8 GHz and Wi-Fi 2.4 GHz

Abstract

RF energy harvesting is one of the various areas in which research is still ongoing. RF electric waves used by devices can be harvested and used for efficiency. This paper demonstrates the efficiency of power harvesting using Circular Polarized Antenna and voltage Doublers to harness that power and convert it into DC voltages to use for self-charging Mobile self. In this project, the development of an energy harvesting mobile antenna is also described, based on research conducted by Dr. Zeeshan. for the purpose of charging a portable cell phone battery from an RF signal available at the nearest BTS (Base Transceiver System) continuously. It should be noted that in the construction of an antenna given bandwidth requirements and display levels it is necessary to develop uniform networks to improve antenna performance and help increase radiation and reduce the loss of response to the desired frequency. Finally, the antenna is designed without network comparisons and, tested by a network analyzer using software called HFSS (High-Frequency Structure Simulator). By making many changes to our Circular Polarized Antenna reference design we have integrated our antenna to operate at our desired GSM band 1800 MHz and 2.4 GHz Wi-Fi band and achieved high power output from the harvested RF power. With the addition of a modified version of the schottky diode-based voltage in the region we reach a high input power of RF. Antenna performance and simulation learned by HFSS software (High-Frequency Structure Simulator). Circuit performance is learned through the software Proteus 8 Professional.
