The study of electric currents flowing through the airframe is important from an EMC standpoint due to the potential to cause severe aircraft failures. Nevertheless, this is a challenging task because of the complex shape, materials, joints, and apertures found in most fuselages. In this paper, we present the design, simulation, and experimental validation of a test fixture intended to emulate the discontinuity between two fuselage panels mechanically attached. This fixture allows several configurations of the mechanical joint, as well as, the insertion of current probes. The main features of the fixture are analysed, such as bandwidth and frequency performance. Subsequently, simulation and S-parameters measurements are used to investigate the performance of several screwed joint configurations.
