Numerical approach for the fast analysis of radiation patterns of antennas in complex environments

A numerical technique for the analysis of the radiation pattern of antennas which interact with complex structures is presented in this work. Different parts of the geometry are isolated and the primary currents are obtained. In the next steps, we compute the interactions between different parts of the geometry and update the total currents. This method is especially well suited for problems that lie beyond the scope of both rigorous and high-frequency conventional techniques, due to computational and/or accuracy requirements.
