Ansys Savant is the industry-leading tool for simulating installed antenna performance on electrically large platforms, including the applications of predicting installed radiation patterns, field distributions, and antenna-to- antenna coupling. Savant simulations are configured through an intuitive and powerful graphical user interface (GUI) capable of importing and simulating complex vehicle and platform geometries that may be hundreds to thousands of wavelengths in size. A key element in Savant’s industry-leading status is its unique extensions to the shooting and bouncing rays (SBR) methodology, known as SBR+. Savant is the only commercial electromagnetic software to extend SBR with simultaneously consistent implementations of Physical Theory of Diffraction (PTD), Uniform Theory of Diffraction (UTD), and Creeping Wave to deliver maximum accuracy within a high-performance ray-tracing framework for large-scale problems.
