Can someone explain me the use of uncalibrated internal port?
My current understanding states that it is used to connect the layout to any external RF SMD (like, diode, transistor, resistor, capacitor, inductor, etc.) in EM-circuit co-simulation with ADS. However, this leads to inconsistent results (refer the discussion: https://www.edaboard.com/threads/273304/).
Besides, it seems it requires the ground reference for an internal port should have an "infinite" ground metallic plate (refer: http://edocs.soco.agilent.com/displ...Momentum#TheoryofOperationforMomentum-1104497). Since, this is possible in Momentum and not in EMDS; thus, it seems I should NOT use internal port while simulating with EMDS.
Please clarify if I am correct with this conclusion.

As I described above, use a perfect conductor cover at top and/or bottom (boundary condition). This is done in the substrate, as usual. It is not infinite in FEM, but that makes no difference. The text that you quoted is not correct and the boundary condition does not need to be infinite.
