Abstract

The development of wireless communication and radio frequency (RF) energy harvesting systems for small electronic devices is examined in this research. An amplifier, rectifier, and transmitting and receiving antennas can all help the proposed RF harvesting circuit generate up to 5V DC for low-energy device charging. A dual-band rectenna is constructed to collect electromagnetic energy from the 3.5GHz and 5GHz frequency bands, which are often used for Wi-Fi and 5G communication, respectively. At 3.5GHz and 5GHz, these bands offer a wealth of electromagnetic energy for harvesting. Suitable for charging laptops and mobile devices, this small and affordable dual-band rectenna interacts with external rectifier and amplifier networks and has an efficiency of over 80% over the 3.5GHz and 5GHz frequency bands. Furthermore, a compact rectangular patch antenna is being developed for use as a transmitting antenna at frequencies of 3.5GHz and 5GHz.
