![]() What you are proposing is a planar gaussian antenna which flattens the cone into more of a fan shape, displays a flat impedence over a wide bandwidth and requires around ten elements of different lengths mounted on a boom support. 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 Art 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 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. Good luck with the project anyway, it makes for an entertaining and enlightening read. Mike G0ULI |

"Gausian statistics refer to the distribution of typically, power over a given area or range. Generally more power is concentrated at the centre of a range with power falling symmetrically either side of a central high point." Art replied: "Correct, very nuch like a band pass filter." In a band pass filter we are interested in frequency response. Mike was speaking of beam forming. There is a difference between beam width and bandwidth. I am still trying to decipher Art`s "Gausian antenna". It would help me if Art didn`t muddle topics. Best regards, Richard Harrison, KB5WZI |

But as yet none have been found as substantial as a clustered radiated elements in equilibrium. What I did find was a indepth explanation of electro magnetism by Harvey on the net that discusses antenna radiation from it's beginnings together with past untruths that are put under the microscope. These papers may not be equal to what is presently understood by scholars but never the less I thought I would share it with the antenna and radiation minded people of this group.. If somebody knows of the existence of a real time proof of Poynting's Vector i.e by a bench experiment I would apreaciate a pointer to where it can be seen Ofcourse if there are some comments to be made on the Harvey papers this would be a good place to put them. Art the Poynting vector is nothing but a way to represent power in 3 dimensions. That is it, nothing more, no magic, nothing worth proving, just a simple statement of energy flowing through a surface. Now if you could prove it wrong that might be interesting, but otherwise it follows directly from conservation of energy and obeys all the related laws. Dave , what kind of idiot are you not accepting Grassian antena theory. I mean just because every Gaussy antenna array present has proven to be less efficent than a standard yagi yo find reason not to think it is the greatest thing since sliced bread. Damned just how thick headed are you? Cant you see what a great breakthrough Gassious antennas are? 8-)) Jimmie |

I have not yet found a description of an actual proof similar to described by the Gaussian Antenna and have found a number considerable number of " attempts" to provide such a proof on the internet. The problem that you have is that the Poynting Vector does not exist as such, so it cannot be proved. It is nothing more than a mathematical nicety that happens to yield a vector product that happens to be in the direction of propagation. It is possible to devise an infinite number of similar vectors that equally well (or better in some cases) describe the energy flow through a surface. There are plenty of derivations of the mathematical relevance of the Poynting Vector available. The Poynting Vector is favoured because it is mathematically simple and describes energy flow adequately in a non-static case. 73 Jeff |

Art Please follow this trail Gauss, Maxwell/ Heavyside, Poynting/Heavyside. Like all theories absolute proof may be unobtainable, gravity is a theory but I am not worried about falling up when I get out of bed in the morning. Jimmie |
