Design of Antenna System to harvest RF Energy for Generating Electricity

Electromagnetic energy harvesting holds a promising future for energizing low power devices in wireless communication circuits. Here we present a RF energy harvesting system that can harvest energy from the ambient surroundings from the radio frequency of 1.42 GHZ to 2.28 GHZ. The harvesting system is aimed to provide an alternative source for generating electricity. The system design consists of a high gain square shaped patch antenna, a RF-DC conversion module and a battery. For a received signal gain (max) of 32.15dBm (1.64 W) at the antenna modules produce a DC output voltage of 6.5 V across 100 k? load. DOI: 10.17762/ijritcc2321-8169.15016
