I found it interesting to read on a particular
antenna page that the antenna future will revolve
around what the person was presenting.

This does not compute to me...
He may well be correct if we are all lemmings but
people who piddle with antennas are a different breed.
Personaly I see antennas gyrating towards smaller
antennas where radiation per unit length will finish
at the top of the heap

Belly dancing antennas? I've never actually seen an antenna gyrate,
but it sounds interesting...

Antenna engineers have become so focussed on the half
wave patterns that they have completely ignored the
low efficiency portions at the ends of a half wave
antenna.

Says who? BTW, there are no low efficiency portions of a dipole.

Future antennas most surely will remove these
low efficient radiator parts

Why remove something that doesn't exist?

together with the addition
of coupling techniques that will help to move away
from the Yagi syndrome,

What is the "Yagi syndrome"? A disdain for antennas that fail to
compete with yagi's?
together with resolving the
of a "lossless" coupling direct to the transmitter

Of all your wishes, to me, this is the most foolish . I think you
should erase this "lossless coupling" from your mind, when it applies
to very small antennas. It doesn't exist, and never will. I don't know
if superconductivity could change this or not....I don't have the
superconductive materials needed for such a test..

that will obsolete the need of matching interface.

You wish...

Ofcourse this is where my intersts lie, but does this
vision of the future match yours or am I thinking
of the impossible?

Well, let me give you a hint....I prefer the largest antennas I can
get away with...I doubt anything will be changing that anytime soon.

One noted Russion scientist stated
that theoretically radiation can come from a single point,
is this part of our future or just an impossible dream ?

How does this relate to small antenna's? I don't get your point
here...

Best regards, and please put your pea shooters aside
and try to get along rather than looking for
ten seconds of cheap glory.

I don't have a pea shooter. I can pee a long ways though, if I go into
a holding pattern for about 5 hours after drinking about 14 cups of
coffee...Maybe we should have a rraa peeing contest....I don't want
any glory, if it's cheap. :/ MK
