Material for manufacturing metal plate antenna

hi,
i designed and simulated a copper plate antenna which is similar to the design shown in here.

Now that i want to manufacture it, i want to know, if there is a particular standard of copper for antenna fabrication? or is there some kind of coating to be done on antenna plate. I live at a place where there is no antenna fabricating industry, so i will have to do it myself.
Please suggest.

Thanks

In my opinion, the things with copper plate are not the big problem. Normally, it's 0.035mm of depth. I suppose that you can fabricate this antenna by enroding the copper at the slot because the dielectric like R4003, FR4 ... are always covered copper on one or two plate, this is standard, so you have nothing to worry about.
