Hello
I'm trying to learn CST and I don't understand well how ports are defined.
For example I found a pdf tutorial that simulates a wifi antenna fed through a coaxial cable.
And they define the port like this:
I don't understand why they just pick the shield of the coaxial and they don't specify the core, neither in a different port.
Another example I can't understand, in this tutorial

Why do they need to pick a port much larger than the microstrip line section?
thanks
