Hi all,
please can any one help me to answer theses questions/
1- i'm working to design a very UWB antenna (from 3 to 50 GHz). i would to perform this design by HFSS, but the problème that i have is: when i set the frequency setup at 50 GHz for analysis, i have the following message: "solution setup 'setup1": given the frequency and model dimensions, an extremely large mesh will be requiered to produce an accurate solution. your model and/or frequency units may be set incorrectly".
The dimensions of the subsrate are (35mm,25mm,0.83mm), the dimensions of the abc box are (135mm, 125mm,100mm), Maximum number of passes is 30, Maximum delta S per PAss is 0.02, Minimum number of passes is 5, and the Minimum converged passes is 3.
So please how can i resolve this problem?
2- On the other hand, please help me to understand the frequency setup analysis????? what means,and how we can choice this frequency for UWB antenna (with large bande of frequency).
Thanks for all, i'll be very grateful for your help.
best regards
