How to use HFSS ideal Phase Shifter?

[RussKy_GoKu]

Hi all,

I am designing a phased antenna array in HFSS, and I want to add ideal phase shifters in between transmission lines. Now I can't use the "Edit Sources options" because I have fewer sources than antenna elements due to the feed network, so I want to add phase shifters in the middle of the feed network before each antenna.
Is there a way to do that in HFSS?

thanks

Do you wish to simulate phase shifter excitation?

Probably the easiest way to do this is to used lumped (internal) ports. Place these inside of your feeding structure, then you can modify the phase shift from the "Edit Sources" panel as you indicated.

If you're just simulating the array, you can just input the theoretical phase

Another option is to go to Project/Insert Circuit Design/ set Workflow None, and from Groups chose TRL.
Add ports to TRL, and you can change the length in degrees of the TRL (which is actually the phase shift).
