Aperture Coupled Antenna

Hi folks
          I am designing an aperture coupled Patch Antenna for my Masters project. I am ready with all the paper calculations and would now like to implement the same in ADS Momentum . Here I am stuck up with a problem i.e. 'Mapping the substrates'
The aperture antenna looks like this 

My queries
1) How do I make a slot (known dimensions) in a ground plane in ADS ?
2) How do I map two substrates with a ground plane(with slot) in between?

I have previously designed and implemented a narrow band patch antenna in ADS Momentum. There I mapped the substrate (only 1) using the Momentum->Substrare->Create/Modify tab.
