I need help with design microstrip antena

Hello.I must design microstrip antenna.Even I have found some tutorials for Ansoft HFSS and also files for this (for Ansoft HFSS).But the problem is that all files are for version 10 but I have only 9.2 and i have seen in the internet links to version 11.
Can anyone help me and give links to Ansoft HFSS version 10 ?
Please -it is very important for me
I don`t want any mistakes whil i will use version 9.2 or 11.
Best regards

Hi cieja,
there's no need to be worried. If you are able to get the 11th version, it allows to open the 10th version's files too. So, get HFSSv11 and open the files made with v10. You can re-save them in HFSSv11 and simulate again.

Bye.

PS--> You may find some slight difference in solution in v9.2 and v11 (if both file's versios are correctly set) but it depends on the way the convergence algorithm is implemented in HFSS11 respect to v9.2 and on the way you set the sweep type, solution frequency and mesh characteristics.
