UWB Antennas & HFSS

[helio1972]

Dear Freinds,
I have tried to resimulate the same antenna as described in Parini's artilce (see attached file) but I can't succes to get the same S11.
can anyboady tell how we can choose the frequency center in HFSS when we simulate UWB antennas?

No one has an answer of this problem.

hi helio:
the result is not very good . though the S11 parameter is like the measured results , the high frequency is not so good , well , it may because i change the relitave CS and there is a warning pops up, i am not sure wheather it leads to the bad result.
well, i will use IE3d to re-simulate it .
