RFID antenna simulation questions

I have been leanring UHF FFID tag design and downloaded an example model called "uhf_rfid_tag.mph". However, from the knowledge I have and comparing with the model, I have several questions:
1. In the model, the layer of the antenna material is assumed to be zero (no thickness), I am sure the conductivity of the material affects the performance of the antenna. Why is is zero?
2. The dipole antenna is a symmetrical structure so if the antenna is only simulated in half and set the surface to be symmetrical, will the results are same as that of simulating a full 3D structure?
3. I am trying to draw a 3D model in Autodesk and then import it into Comsol. I try to draw an antenna on top of the substrate in 2D (without extruding) but it doesnt recognize in Comsol once imported. I tried to play with few importing options but the antenna doesnt show up as it doesnt have a thickness.
4. If I want to use "Parameter Sweep", does the model must be drawn in Comsol? imported model doesnt work on parameter sweep?
Many thanks,
Rock
