In this paper we show how multiobjective optimization can be applied to electromagnetic applications. The optimization algorithms are combined with CAD and mesh generation software, and electromagnetic solvers.
Three different multiobjective optimization methods are applied: one evolutionary method, one method based on scalarizing of the objectives combined with a method for single objective optimization and a multiobjective respond surface method. To demonstrate the procedure we study the optimization of the return loss of a patch antennas at two different frequencies.
