    How to simulate a dielectric immersed antenna in hfss

    I have to simulate an antenna immersed in a dielectric.
    what is the distrance for the dielectric box (radiation)? i noticed that the gain changes according with the distance...

    You want to keep effective lambda / 4 for radiation boundaries and effective lambda / 10 for PMLs. However, if you want correct far field patterns, you will need to go to HFSS -> Boundaries -> Edit Global Material Properties and change the global material from air to whatever the immersed medium that the far field will be measured in.

    Have Fun

    Also, be aware that if your immersed medium has loss, it will matter ;)
