Hy:
I'm a student of telecomunications thar are using HFSS in her project. I would like to know why the results (like parameters S11 and S21of any structures) depends on length of the integration line using lumped ports.
In special, I am Analysing a coaxial to rectangle/ circular waveguide transitions and the results of the parameters S11 and S21 aren't corrects. I am using rectangles for aproximating the coaxials and I'm using like excitation, lumped ports (internal to waveguide). Waveguide material is vacuum, and I have assigned a Boundary type PEC to the external face of waveguide. With this, the results of parameters S11 and S21 in the range of 11-15 GHz are wrong in the order of -10dB, why?. Which is the more correct excitation for this model?.
Thank's.
