Experimental study of characteristics of stripline device prototype based on meander line turn for protection against pulsed excitations
DOI: 10.21293/1818-0442-2023-26-2-14-20
Abstract: The study results of frequency and time characteristics for a prototype device intended to ensure the protection against pulsed ultra-wideband (UWB) excitations based on a meander line (ML) turn are presented. First, the simulation results of the device are briefly presented and the choice of the cross-sectional parameters of the initial turn is justified. In order to design the ML turn on a given PCB area, it is bent into a meander with weak coupling between non-core half-turns, which allowed placing a turn with a length of 2650,6 mm and width of 3.7 mm on an area of 67,3×70,3 mm2 with preserving the prop-erties of protection against UBW influences. The results of measuring the frequency and time characteristics of the manu-factured prototype based on a vector network analyzer (VNA), as well as the results of measuring the radiated emissions using the VNA and uTEM-cell are presented. The regularities of pulsed UWB influences decomposition in the turn are experi-mentally confirmed on the example of idealized and real excita-tions of different durations. The attenuation up to 3.6 and 2.7 times is obtained at idealized and real excitation respectively. The frequency ranges in which the level of radiated emissions is maximal are revealed.
