yes, it needs to be in contact only along the edges... you can create an arbitrarily shaped sheet by drawing a poly-line where the last segment ends at the point where the first segment begins...  in this case, start by drawing a poly-line on the upper top-left corner of the rectangular conductor... then draw the next segment by clicking on the lower-left side of the rectangular conductor. Then connect the next point to one of the faceted vertices of the curved surface... continue along the curved edge with points wherever there are vertices... finally, click on the point where the poly-line started, then move away from the point and right-click anywhere and select 'done'... You should now have an arbitrarily shaped 2D sheet that is in contact with both edges where you can define your port...


Also keep in mind these are differential ports - if they are represented as single ended ports, whether in ADS or AEDT Circuit, you will be shorting one side of the port to your system ground in the circuit model...
