Abstract:  Electromagnetic simulation and electronic design automation (EDA) play an important role in the design of 5G antennas and radio chips. The simulation challenges including electromagnetic effects and long simulation time and this paper focuses on simulation software based on finite-element method (FEM). The state-of-the-art EDA software using FEM novel computational techniques can not only accelerate numerical analysis, but also enable optimization, sensitivity analysis and interactive design tuning based on rigorous electromagnetic model of a device. Several new techniques that help to mitigate the most challenging issues related to FEM based simulation are highlighted. In particular, methods for fast frequency sweep, and mesh morphing as well as surrogate models for efficient optimization and manual design tuning are briefly described, and their efficiency is illustrated on examples involving a 5G MIMO antenna and filter. It is demonstrated that these new computational techniques can lead to significant reduction of time needed for design closure with the acceleration rates as large as tens or even over one hundred.
Keywords: design by optimization; electronic design automation; fast frequency sweep; interactive design tuning; mesh morphing
