WEMA16: Streamlining Antenna Placement and Co-Site Analysis on Electrically Large Platforms

Abstract
Modern aerospace platforms demand multiple RF systems—communications, navigation, telemetry, electronic warfare—competing for limited mounting locations. Traditional co-site interference analysis on electrically large platforms requires extensive computational resources and weeks of iteration, restricting designers to few configurations before design freeze. Using a representative flight vehicle case study, this presentation demonstrates Nullspace's complete workflow for rapid multi-antenna placement exploration: physics-aware defeaturing removing electromagnetically irrelevant details, comprehensive co-site evaluation including mutual coupling, pattern distortion, and platform scattering effects. Fast Adaptive Frequency Sweeps enable frequency-dependent analysis across multiple configurations in hours instead of weeks—enabling design space exploration while configuration changes remain practical.
