What you are proposing is a planar gaussian antenna which flattens the

Incorrect. It is a cluster of elements in equilibrium where all
elements
are resonant as is the array in its entirety. I t all ha sbeen well
defined
in past postings on Gaussian antennas
I could be wrong, but I believe that you have reinvented the log
periodic
antenna.
Yes you are wrong

Thank you for your courteous response. I thought I had to be missing
something. It was of course the fact that the cluster of elements and the
array were all in equilibrium and resonant in their entirety. That's the bit
that is obviously causing people problems and upsetting them
Yes, that is about it, you could also match that same definition
to Poyntings vector but even that comes under fire. There was also
a mathematical anylysis made by an individual contributor
connecting Gauss but that got hammered also. But lets face it they
are amateurs by definition.
although I must
confess I don't quite understand the advantages over existing designs. The
antenna is obviously directional and exhibits gain but apparently not at
levels that would render existing antennae obsolete.
Certainly not, it achieves things other than focussing for gain
which is primarily the intent of the yagi. If the yagi satisfies all
then there would not be a need for other types of antennas
or multi books on the subject. Amateurs concentrate on the word
gain to the exclusion of consideration of other attributes.
The antenna trade magazine feels that the biggest needed advancement
is to get drivers to handle impedances lower than 5 ohm. Weather
people
are striving for minimum cross polarisation. Wi fi is striving for
maximum uniform coverage. Gauss's and Green's functions are being
utilised
to have multi channel operation at the same time using what is termed
a Gaussian antenna so named becaus of iterations used before
transmission.
Thus many things are sought after in todays world besides the almighty
gain.
It is unfortunate that the amateur community refuses the introduction
of antennas based on Gaussian law as well as Poynting's vector but the
fact
is that as amatures they cannot be expected to understand the
underpinnings
of radiation or to visualise a cluster of elements that some would
consider
it as an individual mass. The very idea that a single point of energy
supply
can evoke the emmission of flux from multi radiators that are randomly
arranged
and in equilibrium without reflectors or directors is completely
beyond
their ken and thus want to see it as a bolloxed Yagi.
I see advancement as the provision of something new that may or may
not
provide a clue for major advantage even tho each clue may not
necessarily
on its own be outstanding. By adding the unit of time to both sides
of the
gaussian equation for statics I have provided a correllation to
Poyntings vector
and a antenna array that follows that hypothesis. Existing mathematics
and computor programs confirm this aproach but amateurs have been
seething with
anger at the idea of some thing new as you can see by the comments.
Fortunatly there are some scholars around outside the amateur
community
who have verified independently what I have produced and the days
have
gone over this side of the pond that used to flourish in past glory
days
of ham radio.
Good luck with the project anyway, it makes for an entertaining and
enlightening read.
Yes it has been entertaining for some who relish the idea of slander
and insulting behaviour which is what this newsgroup is famous for.
Basically that is what all things are about now on this side of the
pond
": You are either with us or against us" is now the mantra of the day.
