The experimental antennas are as small as one-
fiftieth of a wavelength and could shrink further.

In fact, commercial Ham antennas with similar efficiencies at similar
scales have been around for decades.

Shrinking them further encounters loss accumulating at the 4th power
of size. This is a very difficult proposition to beat in stale
reporting with the concurrent lack of proven models following after
lo' these 4 years. That is pretty sound evidence of these researchers
having been lost beyond the precipice of an astronomical plunge in
efficiency.
