Fractal antennas and Tesla coils

I recently attented an interesting presentation on the use of fractal
antennas.  I was wondering if anyone was building coils designed to
resonate at multiple, disparate frequencies (e.g. not just w, 2w, etc) or
at least using coils with multiple resonances. I seem to have enough
trouble getting my coil to resonate at one frequency, but I thought
someone out there may have thought of the idea..

Supposing for the moment that you were trying to do the wireless power
thingy, could a broadband antenna help improve efficiency?  If so, is
there a good way to broadcast power (e.g. more than just enough for
a voice/data signal, etc) through one?
