Ever hear of the BOW TIE. Its a sort of Fractal antenna. Having a wide
band. It could be improved by making it a full fractal.
That's interesting. In what way(s) is it improved by making it fractal?
How much is the improvement? Can you point me to a reference about this
which gives some quantitative data?

Sorry, it doesn't. Among the claims, trolls for investors, and
testimonials, where is the quantitative data showing that a fractal
antenna is in any way better than a bow tie, in what ways, and how much?
In other words, exactly where is the evidence on which you based your
statement?


The only "evidence" I have is a "testimonial" by the guy who invented it,
on some PBS show. And they claimed that that's how they pack so much
antenna into a box the size of your thumb. ;-)


And, having a passing familiarity with fractals, it just sounds eminently
plausible to me. :-)


Cheers!

where ';s the beef?
