The Microstrip Line Calculator calculates the characteristic impedance, effective dielectric constant and time delay per unit length of a microstrip line.

It is based on the paper "Accurate Models for Microstrip Computer-Aided Design," E. Hammerstad and Ø. Jensen, Symposium on Microwave Theory and Techniques, pp. 407-409, June 1980.

For zero-thickness trace, the error for characteristic impedance is less than 0.03% for W/h<1000, and the error for effective dielectric constant is less than 0.2% for 0.01
Corrections are made to account for non-zero trace thickness.
