abstract = {This work offers a 60 GHz antenna-based rectenna in millimeter band. In this paper, we describes the concept of wireless energy transmission that allows the transfer of RF energy from one point to another through open space. A parametric study is carried out to monitor the influence of the input power and the number of floors on the performance of rectenna system. It has been shown that the efficiency can reach 54.6% for a load resistance of 100 Ω and an input power of 15dBm. © 2022 IEEE.},

abstract = {The present work propose an optical rectenna based of solar cell antenna operating at 2.4 GHz. This paper describes optically transparent solar patch antenna. To maximize the surface of use, we combine the antenna and the solar cell in the same device. The principal problem of the current solar antenna is the radiating patch which made of nontransparent material and degrades the total solar efficiency. Therefore, this problem can be solved by using the transparent conductive oxide (TCO) thin film as a radiation patch and the glass as the substrate. A topologie of rectifying circuit has been proposed in the present work and the parametric study has been shown that the efficiency RF/DC conversion can reach 73% for an input power of 10 dBm and a load resistance of 4 kΩ. © 2021 IEEE},

abstract = {With the increasing need for high through puts and the scarcity of available frequency, we propose in the research paper new solutions that meet these requirements. Ultra Wide Band (UWB) technology seems a very promising solution. we developed a new small circular modified Microstrip antenna design to lift the bandwidth lock while maintaining a valued performance properties quality. This new antenna consists of a circular microstrip antenna with ring slot inscribed in a patch resonator and a modified partial ground plane with slots to form a single wide bandwidth. Indeed, we studied the performance of a patch antenna made of FR4epoxy substrates (20×20×1.57). The bandwidths range from [3.6 GHz; 4.9 GHz] for a width of 1.3 GHz and a band of [9.7 GHz; 26.7 GHz] of 17 GHz and for frequencies above 27.9 GHz the bandwidth is of the order of 7.2 GHz. Antenna various simulations performance are carried out and obtained tests results are validated with requirements agreement. © 2018 Electromagnetics Academy. All rights reserved.},
