A convoluted strip pulse forming line with zero thickness trace has been designed, which is all-solid and has low characteristic impedance. Through conformal mapping, the calculation method of its characteristic impedance the impedance is derived by converting the convoluted stripline into an asymmetric one. The simulation shows that the impedance will decrease because of trace offset, while the influence of asymmetry could be ignored when the ratio of trace width to the separation between ground planes is large enough. The relationship between asymmetric rate(the distance ratio of trace-upper plane to trace-lower plane) and the impedance is obtained. And the impedance will fluctuate within 5% when the rate less than 3.1, so the influence of asymmetry could be ignored in practical design
