Annotation: The addition of extra conductors to the coupled microstrip line is suggested to improve the protection against ultrashort pulses. Microstrip lines with three, four and five conductors were obtained with the maximal amplitude of decomposed pulses of 3, 3.6 and 4.5 times less, than the signal level at the beginning of the line. The results show prospects for research in the field of multiconductor modal filters.
