Abstract In this study, we present our findings from investigating the use of a machine learning (ML) technique to improve performance Quasi-Yagi–Uda antennas operating in n78 band for 5G applications. This research study investigates several techniques, such as simulation, measurement, and an RLC equivalent circuit model, evaluate antenna. investigation, CST modelling tools are used develop high-gain, low-return-loss Yagi–Uda antenna communication system. When considering antenna’s...
Abstract Yagi antennas are useful for wireless communications because of the directional gain they provide, allowing antenna to concentrate signal in either transmission or reception direction. It is built on a substrate made FR-4, this has return loss −46.85 dB at 3.6 GHz and bandwidth 3.3–4.2 within −10 range, making it ideal use n77 bands. Not only small, with size 0.642 λ 0 × 0.583 , but also maximum 7.95 directivity 8.58 dB. This study investigates several approaches estimating...
In recent years, improvements in wireless communication have led to the development of microstrip or patch antennas. The article discusses using simulation, measurement, an RLC equivalent circuit model, and machine learning assess antenna performance. antenna's dimensions are 1.01 λ0×0.612λ0 with respect lowest operating frequency, maximum achieved gain is 6.76 dB, directivity 8.21 dBi, efficiency 83.05%. prototype's measured return loss compared CST ADS simulations. prediction determined a...
In this study, we have presented our findings on the deployment of a machine learning (ML) technique to enhance performance LTE applications employing quasi-Yagi-Uda antennas at 2100 MHz UMTS band. A number techniques, including simulation, measurement, and model an RLC-equivalent circuit, are discussed in article as ways assess antenna's suitability for intended applications. The CST simulation gives suggested antenna reflection coefficient -38.40 dB 2.1 GHz bandwidth 357 (1.95 GHz-2.31...
Abstract Using a frequency of 915 MHz as an operating point, this project has analyzed and refined the design Sphere Yagi antenna. In CST, we have begun research phase created preliminary for The simulation results been analyzed, then fabrication, testing, measurement carried out. To begin manufacturing process, single-sided copper board is cut into sphere shapes, with length each plate varying depending on size sphere. Drilling machines are used to create hole in plates. As result,...
