Sažetak
The goal of designing a shielded High-Speed Data (HSD) connectors is to find the ideal balance between economy and performance. The connectors are a part of many systems and they influence their performance. The connectors should be designed to avoid possible negative effects on system properties. Thus, it is necessary to analyze the shielding effectiveness of connectors to ensure the electromagnetic compatibility (EMC) of the whole system. The transfer impedance is an effective shield parameter used to evaluate the shielding effectiveness of cables and connectors. Based on the analysis of the limitation of available test methods, a 3D model is developed to numerically calculate the transfer impedance of the HSD connector. Even though numerical methods were used, the theoretical foundations necessary to interpret the obtained results are revisited. The theory associated with cable shielding is revisited through solving known equations for the transfer impedance of a coaxial cable with a braided shield and foil.
