ABSTRACT - A software tool equipped with an electromagnetic field solver is used to create sensitivity tables for 100 Ohm STP cable. Then, directed by the tables, the impact of individual design parameters on attenuation and characteristic impedance is investigated. The design parameters include: lay length, wire conductivity, screen conductivity, insulation loss tangent and dielectric constant, and wire and insulation diameters. It is demonstrated that selection of dielectric constant of the insulation has a critical impact on attenuation and that depending on selected dielectric, one can calculate an optimal characteristic impedance, which leads to smallest attenuation of the STP cable.
