Simulation-driven size reduction of antenna structures using adjoint sensitivities and trust regions

摘要: Explicit size reduction of antenna structures using cost efficient EM-simulation-driven optimization is discussed. The proposed approach directly handles the (as main design objective) while ensuring satisfaction electrical performance parameters by means suitably defined penalty functions. For sake computational efficiency, carried out cheap adjoint sensitivities and trust region framework utilized as convergence safeguard. Our technique illustrated through a compact quasi-isotropic dielectric resonator antenna.
