UWB antenna simulation

Hello, I am unable to reproduce the simulated results for the below reference paper. help me in this regard.





56.rar4. Very Compact Printed Triple Band-Notched UWB Antenna With Quarter-Wavelength Slots.pdf

,,,,,?Copper thickness,,, put o.o35mm!

Thank you for your reply Fiwi sir, i think you have simulated the results in CST MWS. Thickness of the patch and ground plane are not important IMO. Have you got the same return loss graph as depicted in the paper?

I am exciting the antenna with Waveport, is it necessary to excite the antenna with SMA connector, if so can you send the SMA connector design file in HFSS for cpw feeding.
