Expedited EM-Driven Optimization of Antenna Structures Using Gradient Search with Jacobian Change and Design Relocation Monitoring

Design of modern antenna structures heavily exploits full-wave electromagnetic (EM) simulation tools. It is a practical necessity that results from unavailability or unreliability of other evaluation methods. EM-based adjustment of geometry parameter values aiming at improvement of electrical and field characteristics of the antenna at hand (also referred to as design closure) is of growing importance, especially in the case of topologically...
