I recently gave a write up on Gaussian arrays
As a sample which was not directed for any
desirable I laid out the following

All of the elements were placed above each other purely
to make things easier to do plus it being an unusual
arrangement probably never seen before.

Coordinates ( perfect ground) Inches
X Y Z

0 209.46 927.1
0 198.25 973.97
0 172.78 822.86
0 219.83 964.4
0 185.53 922.4

With 1" dia elements
my results were
Impedance 48.5 + j 0.1
Horiz gain 8.12 dbi @ 12 deg
Rc gain 5.11 dbic

Since I am not sure of the capabilities of EZNEC
or other programs
I also supply the following

All elements driven impedances are
6.58 + j56.9
-5.28 - j 37.6
-5.00 -125
9.35 + 58.5
-16.2 - j205

as i pointed out before, and this verifies, you have found one of the
limitations of finite element methods for modeling antennas. very close
spacings between long elements causes un-realizable results. the extremely
low real components of the impedance and high reactive values are symptoms
of this.


Now I need the help from anybody with a engineering degree
which wipes out Richard since his only intent is to ridicule,
or deceive anyway, to confirm the following

For a Gaussian field the energy radiated
by the array as a whole ( feed element 1 )
must equal the sum of the energy
supplied from each individual element.

this is true for any array.


Questions.
1. Am I correct in saying this?
2. Does the above array rank in any way
as a Gaussian array.?

define 'gaussian array' as it applies to antennas that you are describing.

that type of array is not defined in my copies of Jackson's or
Ramo-Whinner-VanDuzer's books, nor does my IEEE antenna design handbook
mention that term. there are references to 'gaussian beams' with respect to
the shape of the fields from feed horns for microwave dishes and other
quasi-optical systems. Some searching of the web also seems to refer to
gaussian arrays, but those all seem to be related to current or power
distribution on elements of an adaptive array.



Frankly, one or more of you is an academic so I really am
pointing at you for direction so I can be sure that my
program has not somehow become corrupted
I am sharing this with you so can you share
your input with me? If you prefer to communicate
by E mail with me that is fine since we know that
the lips of some will spew
