Microstrip line modelling in the presence of interfering metal strips according to their orientation

In the context of PCB technology, this paper deals with the measurement and simulation of propagation from a microstrip line disturbed by a metal ribbon placed just above it. We investigate the influence of the angular orientation of the interfering strip and we highlight the presence of disturbances on transmission S-parameters. Lastly, we propose a model of these ribbon orientation effects, which is validated by the experimental results.
