Hi friends,
I want to design an IFA in FR4,i design the dimension ,but i do not know how to select the trace width,and what will happen about the trace width difference.Anyone can tell me?
Thanks,
 

There is no special formula for trace thickness of IFA, but have to know that IFA frequency bandwidth increases with its thickness.
