Hello. Please tell me how to correctly build a model in CST of a folded dipole antenna consisting of a Yagi array with waveguide excitation ports? Non-discrete sources. VHF frequency range. Maybe there is reference to literature with study of such an antenna.
Having a waveguide port for this doesn't make sense, unless you feed it with co-ax and put a waveguide port on the other end of the co-ax.
The purpose of the work is precisely this. To create a realistic model of the balun in a 3D modeler.
If you have a transmission line, e.g. co-ax, into the balun, then selecting the face of the dielectric will allow creation of a waveguide port. Waveguide ports have to be aligned with one of the primary axes and have a small length of uniform line leading from the port.
Thank you. But my question is connected with the constructive implementation of such a balun in the CST. Is there any reference to an example of the implementation of a balun of the folded dipole in Yagi array?
Your question did not mention a balun at all. CST will model any shape you can make. Design a balun and then model it in CST. You can even design a lumped balun and put it in as lumped elements, but that negates to some extent using a waveguide port as the input. Look up baluns on the internet if you want to know how to design them.
Thanks for the answers and discussion. Yes, maybe I formulated my question incorrectly.
