Question regarding IE3D running infinite substrate

Hello.

I am trying to simulate half-wave dipole antenna on infinitely thick substrate.

I learned that IE3D does have settings for infinite substrate simulation.

However, I heard that IE3D supports 2D.

I am not sure IE3D would support my simulation.

Or, is there other way to simulate this in HFSS?

Thank u.

hello,

you can specify whatever substrate you want. So If you want a substrate with Er=5 that goes into infinity, yo can just specify that in the basic parameter dialoque box. I never had to do this myself, but you may give it a try.

Older IE3D version accept 3D metallic structures and 2D dielectrics. Newer version do also accept 3D dielectrics, but with increased simulation time.
