trace thickness in ADS

Hi, all,

I cannot find the place to define the thickness of a trace in ADS 2011.5.

In older version, I can do that easily. But now, it seems this is impossible. Does anyone know how to set the thickness of a trace? I believe that is an important parameters for antennas or transmission lines.\

Thanks a lot!

Thickness in circuit model or in the EM substrate definition?

I was referring to the trace thickness in the layout window. Thank you

And that shd be em simulation, but not substrate thickness, which i can define

Why do you want to set a trace thickness in layout? Does not make sense to me, because the layout is 2D.

I don't understand your problem. You can set the thickness, see screenshot

Thank u！thats wat i am talking about.

Btw it is 2.5D instead if 3D actually. I care because the skin depth factor. Need to consiser the thickness.

Sure, that is why I asked about circuit (model based) simulation or EM simulation.
For model based simulation, you specify the thickness in the substrate block (MSUB).
For EM based simulation, you specify the thickness is the substrate definition.

Thank you very much!
