Hi,
I've built the HFSS example of Magic Tee. I was checking the phase information. Surprisingly I'm getting exactly contradictory results.
The phase at the Co-linear ports (2 & 4) is out-of-phase when driven by the Sigma port (3) and the phase at the co-linear ports (2 & 4) is in-phase when driven by the Delta Port (1).

I've attached the HFSS file. Please let me know why I'm getting these results...

Thanks,
-Prakash

Hi Prakash!

It is really a funny problem. I don't have any explanation. If you take a look at the E_field_vector you can see the correct phases.

Anyway, I changed the design a bit (didn't add the arms but subtract from one another) of magic-T. Now you can see correct phases.

Take a look at the attachement.

Hi hkprakash7

I simulated magic-T model a month ago and met the same problem.
When I changed some sizes a little, the phase responses sometimes are correct and sometimes are wrong. I cannt explain it and ignore it.

In theory, it is impossible. I dont know what is the matter with the HFSS.
