Recent advances in Astigmatic Beam Tracing

Asymptotic analysis of antenna on complex and electrically large geometries is commonly used to predict installed antenna patterns on satellites, space platforms, ships, planes and other electrically large vehicles or to predict antenna performance in urban environments. SATSim is an advanced implementation of the Astigmatic Beam Tracer (ABT) technique dedicated to the accurate and fast numerical modelling of antennas on large meshed structures. This paper presents recent developments in terms of minimising computational cost and time consumption on increasingly complex antenna problems using the SATSim software.
