Method of Moments Calculation for Current Distribution on Full-Wave Dipole Antennas

This program utilizes the Method of Moments (MoM) to calculate the current distribution on full-wave dipole antennas. The computational approach treats current distribution as a vector quantity and determines its characteristics by solving the relationship between current vectors and electromagnetic fields through matrix operations. The implementation involves discretizing the dipole structure into segments and applying basis functions to represent current distribution, with the matrix equation [Z][I] = [V] being solved numerically where [Z] represents the impedance matrix, [I] the unknown current coefficients, and [V] the excitation vector. Key computational considerations incorporated in the algorithm include dipole geometry parameters (shape and dimensions), material properties such as conductivity and permittivity, and numerical integration techniques for accurate matrix element calculations. The code implementation typically involves functions for geometry discretization, impedance matrix generation using appropriate Green's functions, and matrix inversion routines using methods like LU decomposition or iterative solvers. This methodology provides comprehensive insights into current distribution patterns on full-wave dipoles, enabling valuable data for antenna design optimization, impedance matching analysis, and radiation pattern prediction. The numerical results facilitate understanding of current standing wave patterns and help identify optimal feeding points and structural parameters for enhanced antenna performance.
