Urgent Help! RFID Antenna Simulated in HFSS for PCB milling

Hi, I have designed the RFID tag Bow-Tie antenna in HFSS attachedAttachment 55003. My main desire is that the antenna simulated should have closer impedance value with the manufactured one after simulation. So for this purpose please check my design environment that is it correctly in place? I am going to mill it on rogers 4003C.
Thanks
