help needed in Antenna Desing using ANsoft HFSS

Hi,

I have come up with a design for a 434 MHz loop antenna (23.5mm * 21.5mm) .
I want to know if i lay this out in HFSS , 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
