Results with parasitics is better than a result with garbage!
1) CST or other simulation programs are nothing to play with. They're expensive, many people put a lot of effort into it to make a great product. And now everybody can download illegally the software (without even paying respect for the developers) and ask questions that demonstrate that they even didn't understand the basic concepts behind these tools.
2) I think, it's not the intention of such products to produce "some" results. They should predict the real performance as best as possible, and the user has to set up the software correctly to get reasonable results. If he don't understand something, he should ask instead just doing something. By the way, CST has a good help function which explains most topics.
Even if he place a ground plane far away or does some other stuff, I'm absolutely sure he will ask one day why there is such big difference between measurement and simulation results. I think it's not the best to teach something.

I did not use discrete ports
You have to place your waveguide ports at the sides of the traces.
