A New Compact Circular Patch Antenna for Wide-band RF Energy Harvesting Systems

For RF energy harvesting applications, a novel wide-band miniaturised antenna design is presented in this research study. The 1.7 GHz to 2.7 GHz frequency spectrum is harvested using a wide antenna. A ground with a slit and a circular microstrip patch antenna makes up this antenna, which is designed to be smaller and to obtain more gain by reflecting back radiation. At cellular communications and Wi-Fi frequencies of 1.8, 2.1, and 2.4 GHz, respectively, it achieves radiation efficiencies of 96.9%, 98.9%, and 98.8%. The suggested antenna is built on a FR4 substrate with a dielectric constant of 4.4 and has an overall dimension of 40 mm x 50 mm x 1.6 mm. This study presents the design, simulation, and production with good agreement.
