Estimating Guided Wavelength and Effective Relative Permittivity

You can estimate the guided wavelength and the effective relative permittivity of a stripline or microstrip line from a given width and frequency.

To estimate the guided wavelength and effective relative permittivity:

1. Select the metal layer on which the microstrip line lies.

If the selected layer is an infinite ground layer, a CPW line is assumed.

2. Click T-Line>Guided Wavelength.

Parameter input boxes appear on the right side of the Estimate module’s window.

3. For trace layers, type the width of the microstrip line in the Width box in the current working units.

4. For infinite ground layers, do the following:

a. Type the width of the first line in the Width1 box.

The units for the line width are the same as the current working units.

b. Type the width of the second line in the Width2 box.

c. Type the gap between the two lines in the Gap box.

5. Type the frequency in the Frequency box, in GHz.

This frequency is independent of the maximum frequency entered in the solution setup.

6. Click Calculate to perform the estimate.

The estimated information appears in the following boxes:

Guided Wavelength	Displays the guided wavelength in the current working units.
Effective Relative Permittivity	Displays the effective relative permittivity.

The estimated guided wavelength and effective relative permittivity correspond to the line width and frequency you specified.
