Roy you have no further to look than this thread and it appeared un der your

Art, I read what he said:

"Sorry, Art, but the reason I don't appreciate your ideas isn't
because I don't understand vectors or analysis from first principles or
because I have some sort of prejudice against something in your background.
It's simply that you're unable to communicate your ideas in a way I can
understand them..."

If you believe that Roy is saying that he doesn't understand vectors,
you're completely misunderstanding what he wrote. You mis-parsed his
(admittedly complex) sentence structure.

He is saying that:

[1] He does understand vectors and analysis from first principles,
[2] He has no prejudice against your background,

but that

[3] You aren't able to communicate your ideas in a way he finds
understandable, and
[4] His failure to appreciate your ideas results from point [3].

Your belief that Roy admitted not understanding vectors or analysis is
purely a result of your mis-reading what he wrote. He didn't say
that. You've acknowledged that you're not a good communicator...
well, I'm afraid you failed to understand Roy's communication
accurately.

Roy isn't alone in his inability to understand what you're trying to
express. I read back through your original question about phase and
magnitude resultants from radiators arranged in a polygon, and quite
honestly there just wasn't enough information in what you posted for
anyone to gain a clear and unambiguous understanding of just what you
were talking about. You wanted to know whether anyone had
investigated or studied such arrangements or systems... but you didn't
specify what *kind* of polygon (regular, irregular, chaotic, fractal,
etc.), what sort of drive or feed arrangments you were assuming to
create the currents to create the signals in the proper magnitudes and
phases, etc.

In short, your query could have been about almost *any* sort of
multi-element antenna, because you didn't give enough information
to enable any reader to figure out what sort of antennas you were
referring to and which you were ignoring.

We can't read your mind. If you cannot express yourself clearly, and
misunderstand what people write in response, then there's just no way
for anyone to help you with your ideas.

As others have pointed out, there are many *decades* of studies,
papers, designs, etc. having to do with multiple radiators in specific
phase/magnitude arrangments. The use of actively-driven phased
dipole or monopole arrays dates back at least to the 1930s, I believe.

It's easy to calculate the resultants for multiple-radiator phased
arrays of various sorts. The hard part is getting each element to
radiate the magnitude and phase you want, in the proper relationships,
with an active feed arrangment that's practical to implement and which
has the other characteristics you desire (e.g. broadbanded behavior).
I gather that there are some simple-seeming problems in power division
and phase splitting for which no good, general solutions are known
even today. Things get even tougher if you want to depend on
parasitic excitement of some of the elements.

Simply adding up phase vectors isn't hard... but it doesn't equate to
designing an actual working antenna. It's sort of like the old joke
about a physicist's cookbook: "First, assume the availability of a
spherical chicken of uniform density." The recipe is easy once you
have the chicken... :-)
