For an antenna problem, such as aperture coupled microstrip patch antenna, we set the source at one edge of the substrate, I think now the reference plane is at this position. If I want to see the impedance of the center of the antenna, how can I shift the reference plane to that place. Maybe there are some wrong for my understanding on this software. Pls help.
deembedding helps? I have come across some HFSS tutorial available somewhere in this forum which tells you how to do this.

You can use deembedding.But be careful,deembeding only make a phase shift from reference plane to the new position.To get accurate result, make the deembedding part be a uniform impedance line.
This is deembedding limitation.
when we try to see the result of impedance.What we need to do is only make the phase
shift from the port the the center of our antenna.So, isn't deembeding enough? isn't the
transmission line a uniform one?
If what you said is right,how to set this part?
Thanks
