Position optimal design of vehicular antennae via space mapping and genetic algorithm

The interference between vehicular antennae is very severe and it can not be controlled by common technique used in electromagnetic compatibility but position optimization design. Simple mathematical models are always used in practical engineering together with experimentation, these sometimes lead to low efficiency and poor precision. In this paper, the models of antenna coupling via the method of moment are introduced first, and on the base of the feature of vehicular antennae configuration the model of antenna position optimization is also brought forward. Then, how to realize the optimization process by using Space Mapping Algorithm and Genetic Algorithm is showed in detail. The method introduced is fast and precise. It is a theoretic support for engineering. In the end, the method is proved to be effective by experiment results.
