Abstract :
The present paper investigates the sensitivity of the transmission properties of a simple stripline model to the copper surface roughness. Different profiles are modeled and analyzed by means of three dimensional full wave numerical simulations. Hammerstad and Jensen analytical formulation is demonstrated to be valid only for a specific profile of surface roughness. A visual basic macro is implemented in order to model random distribution of surface roughness profiles. Numerical results show in this case similar performance of the stripline model.
