MATLAB Implementation of Wire Antenna Method of Moments

The Method of Moments for linear wire antennas provides an effective solution for determining antenna current distribution. This computational electromagnetic technique can be efficiently implemented using MATLAB. The Method of Moments is a numerical mathematical model that enables the analysis and calculation of current distribution patterns along antenna structures. Through this approach, engineers can gain deeper insights into antenna system operations and optimize current distribution characteristics. In MATLAB implementation, key computational steps include: discretizing the antenna into segments using basis functions, setting up impedance matrix equations through testing functions, solving linear systems with matrix inversion algorithms like LU decomposition, and post-processing results for current visualization. Typical MATLAB functions employed might include matrix operations (inv(), linsolve()), numerical integration (integral(), quad()), and plotting functions (plot(), surf()) for result analysis. This method plays a crucial role in antenna design and optimization by providing accurate numerical results that facilitate performance evaluation and design improvements.
