Multiobjective optimization Based on Surrogate Models Applied to Antenna Design

S. Jakobsson, B. Andersson, F. Edelvik. In 9th International Workshop on Finite Elements for Microwave Engineering, May 2008.


In this paper multiobjective optimization is applied to antenna design. The optimization algorithm is a novel response surface method based on approximation with radial basis functions. It is combined with CAD and mesh generation software, and electromagnetic solvers. To demonstrate the procedure we optimize the geometric design and feed position of a PIFA antenna located on a ground plane.
