An efficient technique to provide fast and accurate analysis of wideband surrounded antennas mounted on electrically large platforms is presented and validated in this paper. The hybrid method combines dual-grid finite-difference time domain (DG-FDTD) with iterative physical optics (IPO) to analyze on-platform antenna radiation. In Section IV of this paper, DG-FDTD/IPO is applied to the analysis of a wideband antenna mounted on a vehicle. The ability to address the problem of antenna placement is also demonstrated.
