Determination of coupling of UWB pulses into complex PCB line structures using multi-alignment measurements

In this paper the coupling of UWB pulses into line structures will be investigated. It is of interest to study the coupling into different PCB line structures like they are used by standard PCB routing. Due to the complexity of the structures, it is difficult or even impossible to predict the transfer function over the frequency analytically. Therefore a mockup PCB with three structures has been built and placed inside of a GTEM cell. In order to study every possible superimposition of the coupling waves from different paths, the PCB will be turned into different positions and the maximum will be considered and discussed.
