Re: UWB Antenna

for me CST MICROWAVE STUDIO is better. also it's up to three times faster than hfss.

CST will be fine, but my experience is the accuracy is not that good. If it is only the S11 I suggest use of HFSS. But If you need the radiated pulses, use software in the time domain, CST or XFDTD (this is FDTD) will do.
