Abstract

The EFIE combined with the MLFMA is applied to analyze the radiation properties of wire antennas mounted on complex conducting platforms to realize fast, accurate solutions. Wire, surface and junction basis functions are used to model the current distribution on the object. The application of MLFMA reduces memory requirement and computing time compared to MOM, especially for the antenna on a large-sized platform. GMRES with ILUT preconditioner is applied to reduce the iterative number. Several typical numerical examples are present to show the versatility, accuracy and the efficiency of this method
