Abstract Wire antennas mounted on complex platform combined with conducting and dielectric objects are analyzed in this paper. EFIE-PMCHW boundary coupled integral equations are constructed by using equivalence principle. The surface, wire and junction basis functions are defined to simulate the current distribution on the complex structure and the selection of the basis functions on the boundary of the conducting/dielectric interface is analyzed. Multi-Level Fast Multipole Algorithm (MLFMA) is employed to accelerate the matrix-vector multiplication and solve the loss problem. Application of MLFMA increases the ability to solve the large-scale problem. Numerical examples validate this method and demonstrate the accuracy and high efficiency of this method.
