Antenna Modeling using HFSS --- Help needed

Hi,

I have come up with a design for a 434 MHz loop antenna (23.5mm * 21.5mm) . It is about 1.5mm wide and about 1 mm thick.

I want to know how to lay this out in HFSS , after laying it out will i be able to extract the parasitic resistance, Inductance of the loop and also radiation resistance.

Also i want a very narrow bandwidth of about 4-6MHz. can u suggest me a tuning circuit for this.

Thanks
