Abstract

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.
