A hybrid approach for modeling complex antenna systems on vehicular platforms

The use of multi-antenna systems on vehicular platforms, for the implementation of ad-hoc wireless network architectures, is typically hampered by the problem of co-site interference between transceivers loading neighboring radiating elements and the impact of the platform on the radiation pattern. This paper presents a rigorous, full-wave analysis of effects pertinent to vehicular multi-antenna system performance, based on a hybrid time/frequency domain analysis that combines the method of moments (MoM) with the finite difference time-domain method (FDTD). For the fast solution of such problems, MPI-based parallelization strategies are developed. Applications where the combined MoM and FDTD simulation of multi-antenna systems sheds light on the serious impact of mutual transceiver interference on wireless network operation are provided.
