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!

The highest gain in smalllest size would b obtained by using focused
wave antenna antenna, inhelical mode basd upon your description

go here and contact me diectly for fetails may have smaple or can
fabricate based upn your specifiation. Nothig like it on the market!
Patent is new and full marketing budget crippled along with creit maret
so lauch delayed. So its business ti business right here, Good news is
the you get to speak with invetor/builder an producer i on emai :-)

short power point here

As an independant producer and start-up would be very responsive and
appreciative of your support and queries. Can aslo locate front end
amplifiers inside anna eleiminating front connector loss. that last .035
db is hard to obtain any othe way with a connector beween any antenna
and front end so we put front end inside anteanna substrate and your
system will out perofrm all otthers!

Lifetime antenna, virtually perfect SWR, no moving parts, guaranteed a
lifetime, etc., etc.

AND! I bet I can find some to give testimonials to it being an
"excellent antenna." You know the game ... idiots are easily taken
advantage of ... :-(
