How to calculate MCFIL (W,L,S) in ADS? Pls help me!!!

Hi, I am designing band pass filter with centre frequency :2.45 GHz by using Parallel Coupled-Line in ADS program. My problem is i don't know how to calculate MCFIL (width, length, space) because there is not MCFIL in line calc tool. Can you show me how to calculate MCFIL(W,L,S) in ADS program pls ?

The parameters should be optimised.

Use the ADS "Designguide" for passive circuits.
It is described in detail in the documentation/help.

thank you! I'll try it.
