Antenna Design through Space Mapping Optimization

For the first time, we apply space mapping to antenna design. We exploit a coarse-mesh method-of-moments (MoM) solver as the coarse model and align it with the fine-mesh MoM solution through implicit space mapping and output space mapping. A novel local meshing method avoids inconsistencies in the coarse model. Our new user-friendly SMF system optimizes the impedance of a patch antenna in four iterations. In a double annular ring antenna the finite ground size effect for the MoM is efficiently solved and the design specification is satisfied after only three iterations
