Radio frequency (RF) harvesting technologies are bewitching a huge number of people as they are enormously available in the atmosphere. These energies are received and converted to useful DC energy which can be used to charge electrical devices which need low power consumption. Here, in this paper a microstrip square patch antenna operating at 2.45 GHz is proposed having a dimension of 29.2mm × 29.2mm, which is fabricated on a low-cost FR4 substrate having a dielectric constant of 4.4 with a thickness of about 1.2 mm. L-shaped matching network is designed for maximum power transfer between the antenna and the rectifier. HSMS-2850 zero bias Schottky diode is used as a rectifier. The RF-DC rectification is done with an efficiency of 42.8% at -7dBm at 2.45 GHz.
