This contribution investigates the approximation of a well-established immunity test method for electronic equipment by an alternative test method, which so far has only been applied to electronic equipment in aircrafts. The alternative method can provide a similar test environment under certain test conditions, yet offers additional advantages with respect to practical criteria like time and cost saving. It is thus promising for further industrial applications, such as the automotive industry.

The response of antennas with nonlinear loads is investigated. In this contribution we present a method capable to perform simulations on antennas with multiple nonlinear loads that are less time and memory consuming than traditional proceedings. Moreover, these methods also contribute to a better understanding of observed effects. This is shown using an antenna with two nonlinear loads. A deep insight on how nonlinear loads affect the reception behavior of an antenna will be provided.

In this contribution the effects of repetitive pulse excitations on linearly and nonlinearly loaded antennas are studied on the basis of equivalent circuit models. This is important to understand in the context of Electromagnetic Compatibility possible nonlinear effects which often are not included in the analysis. It is found that a surprisingly large capacitive effect can be produced which has no counterpart in the linear case and is accompanied by the storage of unwanted electric energy.
