fraunhofer zone
Hi, guys!
I became interested deeper into zones of antenna - I mean Rayleigh and Fresnel as "near zone" and Fraunhofer as "far field".
I need your comments...
Is the difference between these zones only in simplifying Green function exp^{-jkR}/R resulting in Fourier transform when considering far field?
Or there are some next effects associated with antenna function (transformating process of guided waves into free space)??
What do you think??
Thank in advance,
Eirp
