Electrical properties optimization of stripline for EMC testing of automotive parts

This paper is focused on optimization of electrical properties of 50 ohm stripline which was described in international standard for the automotive industry ISO 11452-5. The standard shows the dimension of the stripline but information about impedance matching is missing - and this information is crucial for a power amplifier connection, especially in terms of VSWR parameter. In this paper connection possibilities between stripline feeders and an input / output coaxial connector are shown, simulations results describe dependencies of the VSWR to the dimensions and shapes of the stripline feeder in the point of connection to the connector.
