microstip ultra wide band antenna desinge uising CST

I design ultra wide band micro strip antenna using HFSS , when i make to it export *.sm3 to run it on CST i get different result
can anyone help me it's my thesis in mater
thanks all

Are u sure that dimension, mesh, frequency, boundary and background settings are correct in CST? This could be common for CST troubles.

thank you for your fast reply
how can i check for these setting lm new in cst

Solve tab (it is located in one row with File/Edit/View etc) - there you have to set correct units, background material, frequency & boundary conditions. Also mesh tab -> global mesh properties allows you to edit mesh cell amount for your model, it is critical to have high mesh cell amount in order to get precise results.
Use help buttons, CST studio has really good help info.

whats your problem? whats your HFSS and CST version?

hfss version is 12 and cst is 2009

when u export the .sm3 u should extract result by ACIS 16 and dont use higher than this

thank you for your fast responce, but do you mean by extrat the result is import it by cst?
or what do you mean by extract the result?

i try it dosn't work
