Physics-based simulation, such as the finite element method (FEM), has been the cornerstone of antenna design for decades. As computational efficiency improves year over year, so has the demand on size and scale of applications. No longer is simulation of the isolated antenna adequate as vehicle integrators (aircraft, satellites, automobiles, etc.) expect full installed performance assessment via simulation as well. Thanks to myriad computational techniques and the resourcefulness of developers, hybrid methods enable enormous scale that include small RF components and antennas as well as interactions with the much-larger platform. This can be extended farther by including relevant features of the environment including terrain, buildings, and other objects and actors. Furthermore, the combination of installed antenna simulation with digital missions, such as a flight dynamic scenario, increases the fidelity and usefulness of the overall virtual prototype. In this presentation, we provide an overview of simulation techniques and demonstrate the first advantage of large-scale antenna simulations. Next, we demonstrate the power of digital mission engineering using the example of interference characterization and mitigation between a 5G base station and an airborne radar altimeter.
