Calculating single ended impedance

Click on the structure type from the Structures Bar.

Select the dimension units (mils, inches, microns or millimetres) from the Units option group.

Enter the values for:

H1 (Height) — dielectric thickness

W1 and W2 (Width) — signal trace width (allowing for finished etch factor)

T1 (Thickness) — signal trace thickness

Er1 — dielectric constant

into the associated text boxes and press the Impedance Calculate button. The calculated impedance will appear in the Impedance (Zo) box.

Add explanatory notes on your particular construction, if necessary, in the Notes text box.
