Dears,
I hope, find you well.
I have a system that consists of two horn antennas and a structure.
I need to put a one-horn antenna in front of the structure and rotate the second horn around the first horn antenna and the structure to find S21. I doing this by CST.
But when the simulation starts this message appears "Waveguide ports must be aligned with Cartesian coordinate planes for the transient solver".
I think that is because of the rotation.
How can I solve this problem?

I have had to put extended curved feed lines to join the plane I wanted with the coordinate planes where I could put a feed. You can build the curved lines using parameters so that they adapt for different angles, with the same phase length for instance. Otherwise use discrete ports, which might not be too bad for your application.
