Simulation objects to be used as unintentional radiators

Electronic devices may act as unintentional radiators. Hence, the prediction of their breakdown behaviour is not possible by design. Instead, time-consuming measurements are necessary to determine their radiation patterns. Stochastic approaches help to do approximations, but need to be validated e.g. by numerical field simulations. In this paper, simulation objects are created by the use of the software FEKO which can be classified as unintentional radiators. This classification is newly defined in this paper. It refers to the characteristics of the maximum directivity in dependence on the electrical size.
