Hi:

A month or so ago I say a PBS piece on fractals. The piece claimed that
the "technology" is used to make the antennas for cell phones.

Have any amateurs used "fractal technology" to form their antennas?

-sigh-

Any? Yes.
Many? No.

Also, I note that "they" market HDTV antennas that are about the size of a
book. Do these things work?

They work about as hard as Bernie Madoff worked.

The most enthusiastic fractal supporters here are those who never
built any, couldn't show you a design if they were forced to google
for one, and pound their breast about how modern inventors are reviled
in their own neighborhood. The most successful merchant who has dared
post here would sue you if you tried to make your own.

What's inside them?

Wire (metal). Same as any antenna.

What makes you ask?
