Again, the word "ground" is poorly chosen and confusing. Earth,
indeed, is not a necessary element of the antenna. A far better
word is "counterpoise" -- that is, some conductive
wire/plane/body that serves as a "return" for antenna current
and, hopefully, lowers the total loss component of the antenna's
impedance. Depending on the geometry and dimensions of the
counterpoise, the field that the counterpoise radiates will
contribute positively and negatively to the total radiation of
the antenna in various directions, and its interaction with the
field of the main antenna wire will help determine the total
vertical and horizontal radiation pattern.
The bottom line is, the MORE copper (or other conductive
material) in the counterpoise, the better, whether its more short
radials or a few longer ones.
