Inductance of microstrip line strip¶

The inductance of the microstrip line can be calculated from its physical dimensions.

inductance¶: inductance of the strip.

Symbol:: L
Latex:: \(L\)
Dimension:: inductance

length¶: length of the microstrip.

Symbol:: l
Latex:: \(l\)
Dimension:: length

width¶: Width (see length) of the microstrip.

Symbol:: w
Latex:: \(w\)
Dimension:: length

thickness¶: thickness of the microstrip.

Symbol:: t
Latex:: \(t\)
Dimension:: length

specific_inductance_constant¶: Constant equal to \(2 \cdot 10^{-4} \, \frac{\text{H}}{\text{m}}\) (2e-4 H/m).

Symbol:: L_0
Latex:: \(L_0\)
Dimension:: inductance/length

law¶

L = L_0 * l * (log(l / (w + t)) + 1.193 + 0.2235 / (l / (w + t)))

Latex:: \[L = L_0 l \left(\log \left( \frac{l}{w + t} \right) + 1.193 + \frac{0.2235}{\frac{l}{w + t}}\right)\]
