Hi All,
I think the most important thing is to take into account the border between the Near-Field vs. the Far-Field of the antenna. The formula is:
Rff=(2*D^2)/(Lambda)
where D is the largest dimension of the antenna and Lambda is the wave length.
So, for panel antenna, 2m long and working in 900MHz band, Rff=24m!!!
