Hi,
How do I determine the thickness of the ground plate of a 1GHz monopole antenna?
Thank you.

Metals other than copper will give the same order of magnitude of skin depth. What you need is a large area of ground plane under the monopole. I would say a radius equal to the monopole height would be a minimum, and maybe 3x the radius would give as much benefit as you could get.
