Limitations of a stripline for immunity tests on road vehicle components

The application of the stripline for immunity tests is described in the standard DIN ISO 11452-5. In this paper the electrical characteristics of the stripline and the related limitations were determined. At certain frequencies high field strengths were measured beyond the test volume. This limits the application of a stripline for immunity tests, which causes additional stress to the periphery and the EUT. To lower the field strength in these areas, some approaches were evaluated.
