A Dual-Band High Efficiency Fractal Rectenna for RF Energy Harvesting Systems
A novel dual-band high gain fractal antenna designed at 2.45GHz and 5.8GHz is developed. The radiator patch, partial ground plate, quarter wavelength transformer, and dielectric substrate are the four primary structures that make up the fractal antenna. The suggested antenna's primary use of the fractal technology is to enable the second operating mode by lengthening the current channel to increase Omni-direction. The antenna is made of FR4-Epoxy material, and its r and tan values are 4.4 and 0.02, respectively. CSTMWS software is used to mathematically assess the antenna performance. Low return loss at the intended frequencies results in a good match. At 2.45GHz and 5.8GHz, a dual-band system with a significant gain is shown. This antenna is suggested for use in applications involving radio frequency energy harvesting. Finally, the antenna performances are measured for validation.
