Also, the second stub should produce a susceptance equal to b s2 -j0.73 to move us to the center of the Smith chart. For other uses of the term Smith diagram, see Smith diagram (disambiguation). As shown in the figure, a short-circuited stub with a length of l s1 0.195 produces the susceptance b s1 -j0.36. ![]()
