Abstract

In this paper, schematic model of an RF energy harvesting circuit coupling with a multiple ISM band Microstrip antenna has been presented. The overall dimension of the antenna is (43 × 30 × 1.6) mm³ and simultaneously operated at 2.4 GHz (directivity: 2.25 dBi) and 5.8 GHz (directivity: 4.33 dBi) respectively with quasi omni-directional radiation pattern; which could be suitable for wireless sensor network (WSN) or any wireless device adopted to operate in ISM bands mentioned above. Lastly two different values of load resistance at the output of the rectifier for different ISM band frequencies have been found out to recycle optimum power in microwatt range to empowering ultra low power wireless sensors.
