Effective Dielectric constant Vs frequency plot of microstrip line using ADS

Hello
I want to plot the variation of effective dielectric constant of a given microstrip line (say, 25ohm microstrip line on a substrate having a relative permittivity of 10.0 and a thickness of 0.65 mm of example 3.8 pozar 4th ed) using ADS. Please suggest me steps to do it. The plot from pozar is attached.
I have seen that linecalc does give me the Keff but is there any to get the variation over a frequency range?

Thanks.

Have you tried a Co-Simulation with the PCB + Schematic Model?

Hi chiques , thanks for responding. After not getting response here, I posted this question to microwave101, and I got the solution.
