ADS 2009 how to properly define PCB stackup for simulation.?

Hi,
im using a roger material RO4350B for PCB design.Can someone tell me how to properly specify the pcb material in ADS 2009.

Thanks

Are you trying to define an MSUB (substrate object) in the Schematic tool, or using the PCB in the Layout tool for usage with Momentum?

Hi,
I'm quite new to ADS..Actually i wanted to know in terms of PCB in the layout tool for usage with momentum.

For the dielectric, you need dielectric constant, loss factor and thickness.
For the metalization, you need conductivity (pure copper = 5.8e7 S/m) and metal thickness.
