If I want to use the EGaIn and PDMS (SylgardTM 184) for an antenna design, what properties do I need to enter in ANSYS HFSS?

On ANSYS HFSS, I'd like to construct an antenna using the materials stated above. So, if I can get the properties with the correct values to put in the software during simulation, that will help me.

Which software might be helpful to design and simulate the 3D shape of the planar/nonplanar microstrip/any antenna?

I am experienced with the antenna simulation using ANSYS HFSS and CST. But now I am working in an additive microsystems lab and want to move to 3D shape antenna simulation and printing.
