Abstract. The development trend in radio-electronic equipment (REE) is toward miniaturizing components while maintaining functionality. This, however, increases the susceptibility of REE to various types of electromagnetic interference, with ultra-wideband (UWB) pulses being among the most hazardous. Stripline devices based on a meander line (ML) turn with modal decomposition can be used for protection against such UWB pulses. As their implementation can vary, this paper investigates two ML turn structures with broadside coupling: one with a single ground conductor and another with two. The paper evaluates the influence of conductor width and the spacing between signal and ground conductors on a range of the turn's characteristics. Based on a preliminary time-domain analysis of both structures, their optimal parameters were identified, and two prototypes were fabricated for experimental investigation. Frequency-domain analysis demonstrated that the addition of a second reference conductor increases the number of maxima and minima in the frequency response of the transmission coefficient; however, it also improves matching with the transmission line, thereby increasing the cutoff frequency. Time-domain analysis revealed that the electromagnetic coupling between the signal conductors is excessive, with the output attenuation being determined by the level of the primary component (crosstalk). The levels of the subsequent modal components, however, are lower. Adding the second ground conductor increases the UWB pulse attenuation by a factor of 4.16. This result was confirmed by the calculated N-norms.

Key words: radio-electronic equipment, electromagnetic compatibility, protection, ultra-wideband pulse effect, modal decomposition, electrodynamic modeling, measurements.
