Gaussian antenna planar form
Since in the past I noted that amateurs
preffered their antennas to be planar I thought I would force Gaussian elements to be constructed some what in line like a yagi but ofcourse spacings will go where ever they want to attain over all equilibrium. The results are as follows when striving for maximum gain. ( 14.25 Mhz) # el boom lth inches gain dbi 2 125 12.85 3 454 14.96 4 460 14.85 5 451 14.98 6 448 14.89 7 440 15.18 8 441 15.20 9 434 15.18 10 434 15.13 A gaussian has a natural good reasonable front to back so I left that out of the equation. The above did not show any variation in band width ie it stayed around 65 degrees so there is no focussing effect around which a yagi is designed As can be seen from the above, after you get a length of approx 34 feet no amount of extra elements added is going to provide more gain or change in radiated pattern and this pattern will be achieved with as little as 3 elements. A normal gaussian normally moves to a cubical volume similar to a stacked arrangement while still only requiring a single feed point so later I will take a look at that. From the above one can see that approx 15 dbi is the most that can be expected from a forced inline array with the pattern of radiation staying constant showing that max efficiency has been reached. I will leave it to others to give their take on the above listing. Art |
