In this article, employing the Method of Moments for computing electromagnetic fields of wire antennas is highly significant. The Method of Moments serves as a numerical computational technique that accurately simulates the propagation and radiation of electromagnetic fields in wire antennas. Through MATLAB programming implementation, we can efficiently execute this computational method and obtain precise results. The implementation typically involves discretizing the antenna structure into segments, formulating integral equations for current distribution, and solving the resulting matrix equation using MATLAB's linear algebra functions like backslash operator or linsolve. Mastering both the Method of Moments and MATLAB programming proves extremely beneficial for researching and designing wire antennas, particularly for impedance calculation, radiation pattern analysis, and near-field/far-field computations.
