Transient analysis of installed antenna performance

The broadband compact source approach enables detailed antenna models to be replaced by equivalent radiating surfaces for efficient installed performance analysis. The broadband phase shift technology can further enhance transient analysis for both detailed and installed antenna simulation. Two applications were presented: a circularly polarized helix antenna installed on a Humvee vehicle model that is feasible to simulate on a mid range laptop and a normal mode helix mounted on an electrically large aircraft model, which demonstrates some of the potential scope of this approach.
