We should define "ground" while we're at it.
If antenna emits electrons (longitudinal Tesla waves) than the ground
is
the
source of them.

Having built one of these things or very similar (or more properly, my
tween daughter did)..

Hook a 6-10 foot long piece of wire to each of the clips and stretch them
out and it works pretty well. In my case, we threw a hunk (precision
measurement.. probably about 10 ft) of wire over the curtain rod, and laid
the other one out across the floor, transmitter sitting on the desk.

The "other one out across the floor" works as the chassis.
The chassis is enough for the small power at higher frequencies.
Your phone cell has the chssis (ground) also.
