The inductance of the shorted slotline and The capacitance of the open microstrip

Hello,

Pls, does someone knows how can we determine the the inductance of the shorted slotline (Ls) and the capacitance of the open microstrip (Coc) ?

Moreover, what about the length for microstrip and slotline. Have we always taken them equal to quater wave length?

Thank you in advance,

N
