Multiband behavior of wideband Sierpinski fractal bow-tie antenna

interesting paper..

The big benefit (from a cursory reading).. is that you have a more
consistent antenna pattern over the frequency range, which the vanilla
bowtie does not. And a somewhat wider match bandwidth. (mostly extending
it to higher frequencies)

There is apparently a "big benefit" for some applications
contrary to the nay-sayers on this newsgroup. Apparently,
the self-symmetry of fractals leads to some predictability
as far as wide-band response goes.

Nothing magic, though.

Don't remember anyone saying that fractals were magic. They
certainly obey Maxwell's laws. I suspect their advantages,
like their straight-wire cousins, lie in the predictability
of their mathematical models.
