F-antenna board height

I am placing a F-Antenna on a FR4 board and had a few questions :

- Why does the F-antenna need to be on 2 sides even though an antenna switch is used (e.g. NCB/SRB board)

- what height should I use for the board, i don't have a NCB board with me but I was hoping for a 0.062 inch board (any idea if dielectric properties of FR4 at 0.062 inches will be okay with the F-Antenna?)

- what's the minimum clearance (left and right) I should keep with the antenna?

I've seen the compact antenna's data sheet but it doesn't seem to explain these points.
