For what it's worth, you might want to check out the ARRL antenna
handbook. It isn't exactly a study, but it gives data related to the
different number of radials and their respective lengths in
relationship to the antenna efficiency.

When someone asks me what's the optimal radial ground screen, I mostly
answer: "120 radials with a length of 0.4 lambda".

This answer is somehow fixed in my mind, based on a study and
experiments undertaken long time ago by ...?

Does anybody have a pointer/link/url to this study or can someone
deliver me more details ?

I already did some Googling, but could not find the article I once
red.

Thanks in advance,
