thickness of the conducting patch and ground plane in MPA

about the thickness of conducting patch in microstrip antenna, what is the suitable value or practical value when the material is cooper? Thanks!

17 μm or 35μm

Is there any document that i can citation?

Try to derive the answer yourself http://en.wikipedia.org/wiki/Skin_effect

Just look at the copper thickness options for PCB material. Example here:

And think about the aspect that FvM mentioned (how much copper thickness makes sense in the presence of skin effect...)
