Abstract. The results of the analysis of the ultrashort pulse (USP) decomposition into a sequence of pulses in a turn of a meander microstrip line with two passive conductors are presented. Various variants of the terminations of the passive conductors of the turn are considered and the optimal parameters of its cross-section are obtained according to the criterion of the minimum amplitude of the output signal. An analysis of the influence of changes in the geometrical parameters of the line under study on the delays of each decomposition pulses and the USP amplitude at the end of the turn was also made. Conditions for USP decomposition are formulated. The results of optimizing the geometrical parameters of the line, considering the technological capabilities of the company "Rezonit" according to the criteria of USP decomposition and minimizing its amplitude are presented. Also shown the results of folding the line into twenty-one minor turns. It was found that the reducing distance between minor turns enhances signal distortion and reduces its maximum amplitude at the line output. This folding made it possible to significantly reduce the size of the line. Attenuation of the real impact signal from the generator of the S9-11 oscilloscope in different software up to 10.6–16.1 times was obtained.
