A General Integral Equation Modeling Method for Analyzing Complex Wire Antennas with Junctions

The general method of moments (MoM) for crossed thin wire structures is an easily overlooked key technology, and few scholars have classified and discussed the treatment of the boundary condition on crossed thin wire structures in detail. In this paper, a robust method of moments (MoM) approach is proposed for complex thin wire antennas. Based on the structural characteristics of thin wire antennas, several important steps are presented in this article: basis function selection, integration kernel processing, degree-of-freedom reduction, and basis function elimination. These steps form a systematic solution, and the correctness and the efficiency of the algorithm is demonstrated through numerical examples.
