Dear all,
For the original design, the copper
thickness at toppest and lowest PCB is 1.5oz. If
we change it to the 0.5oz or 1.0oz thickness, what
were the effect for the PCB antenna and the RF trace
path? (The PCB antenna and the RF trace path are
on the toppest and lowest PCB) Do I need to re-design
the PCB antenna dimension and the width of the RF
trace path after I change the thickness of the copper?
thanks

Hey Cheng, copper thickness will not make much difference.
Take a look at the effective trace width and and
substrate height equations and you will see trace
has a very small effect. Nevertheless, you will
probably want to adjust it to get maximum performance,
particularly when allowing for ecthing tolerances.
Hey! the pictures worked! Good luck
to you. tbone

How about the PCB antenna?
thanks

The answer should be the same for the antenna.

From my experience,
the effect of copper
thickness is negligible. Go and build your antenna...

same here. If you model it in HFSS, you see barely
any difference between 0.5 and 1.5oz copper traces.
Also, you can safely model the trace with an infinitesimal
sheet.
FYI, I have seen this for frequencies
from 1-6GHz...
