Design of Rectenna in the Global System for Mobile Communication/Universal Mobile Telecommunication System, Long-Term Evolution and Wireless Fidelity Bands

Our research work in this paper takes a multidisciplinary perspective, combining concepts from electromagnetism, antenna theory, power electronics, and mathematical modeling. By exploring recent advances and contributing to the rise of energy-efficient technologies, this study aspires to play a key role in creating sustainable solutions to meet the growing needs of our connected society. Thus, we set the objective of designing and optimizing Rectenna energy conversion devices (antenna plus rectifier) at very high frequencies such as the 1800 MHz, 2100 MHz and 2500 MHz bands. We designed under Ansys HFSS and ADS, three single-band rectenna operating respectively in the GSM/UMTS, LTE and WI-FI band. The simulation results showed a lower reflection coefficient of −22.12 dB, −17.70 dB and −28.51 dB at 1800 MHZ, 2100 MHz and 2500 MHz band respectively. These results also gave gains of 3.28 dB, 7.11 dB and 5.65 dB respectively at the 1800 MHz, 2100 MHz and 2500 MHz frequency bands and a radiation efficiency greater than 96% in all 3 bands. Finally, after a broad comparison of the materials constituting the substrates, we obtained a rectenna of 60% efficiency which exactly meets the set specifications.
