RE: NEC-LIST: Small antennas: can they me multiply resonant?

If you define a small antenna as an antenna operated below its lowest
natural resonant frequency, the question disappears (lumped components must
be disallowed).

Subject: NEC-LIST: Small antennas: can they me multiply resonant?

Dear List,

Revisiting the arguments about the CHU limit on Q for
small (very small) antenna structures, in the light of
my comments about multiple resonances, can a structure
which is very much smaller than the radian sphere
contain multiple radiating resonant elements, or is
it necessarily the case that small antennas are only
singly-resonant?
