Antenna design, electromagnetic dispersion, wave propagation, and other electromagnetic phenomena are some of the many computer-based approaches and techniques that are included in the field of computational electromagnetics (CEM). Within the scope of this research, an overview of the ideas, processes, and applications of computational electromagnetics in the investigation and resolution of difficult electromagnetic problems is provided. The purpose of this research is to investigate the fundamental ideas of electromagnetics and the computer modeling approaches that are linked with them. This is accomplished by combining the literature, theoretical frameworks, and applications from the actual world. The research also investigates the application of computational electromagnetics to antenna design. This is a field in which radiation patterns, impedance matching, and antenna designs can be optimized through the use of numerical simulations. Using parametric studies, electromagnetic modeling tools, and optimization approaches, it discusses how to improve antenna performance, reduce interference, and conform to design criteria. Moreover, it explains how to optimize antenna performance. The ethical implications of this study is to enforce the credibility of this field of study to the developmental aspects of electromagnetics in telecom industry and to reflect its significance into an effective deliberation using different techniques as adapted in this project.
