Virtual tolerance study for antenna design

Product design usually requires a significant number of prototype samples in order to optimize specific performance parameters. Furthermore after the completion, it is not clear how robust the design will be regarding mass production tolerances. Even if one can monitor this with a certain effort in the production line, the design process is already complete and it is very expensive to correct potential design errors. In order to simplify the design process, and to take these tolerance risks into account, a combination of statistical and stochastic techniques combined with computer-based simulations will be presented. The method will be illustrated through the case of an antenna design for radar applications.
