That is exactly correct.

Thanks. However, having you endorse my pontifications makes me worry
that I may have said something wrong, or made a mistake. I'll double
check.

The fractal antenna is an optimised meander
antenna where
the radiator "packing" per unit space is superior. It is just that a
fractal pattern has a
mathematical background where impedance can be garranteed where-as a
meander line design is subject
to human error.

There are various tests for randomness.

Random number generators are well developed.

I see no reason for "human error" unless you use a coin toss or dice
throw to design your antennas, which would be quite tedious.

I see no reason why one antenna should be seen as
"better" than the other
if the radiating length and the unit areas are the same.

I do. Trying to shoe horn efficient radiators inside a small package,
such as a cell phone is not a trivial exercise. There are lots of
compromises that can be made if the design is constrained in size,
such as tolerating a high VSWR, strange pattern, and bandwidth
limitations. Incidentally, the primary limiting factor is size,
followed by SAR (specific absorption rate). Gain and pattern are
lesser priorities. VSWR is somewhere near the bottom.

I also see
this as another example where people talk down on this antenna
as a way of resisting change.

Resisting is a complex problem, that includes imaginary parts. Any
reactance introduced into your change will convert your resistance
into an impedance. Think of it as people impeding change, not
resisting change.

Obviously industry see it as
particularly usefull especially with encapsulated designs and Chip is
making a lot of money
despite the dirisivenes of the "experts" on the newsgroup..

Ummm.... where do I collect this money? I could tell a few stories
about chip antenna companies, but I'm sworn to simulated ignorance.
