If an antenna was really matched to its feeding objects, then all the energy
that was not radiated (as in short antennae, for example) would pass back down iinto the feeding objects. However, in order for there to be a reflection back into the antenna from the feeding objects, there has to be a mismatch (fundamental transmission line theory), and therefore, for the energy fed to antennae to stay there, there has to be a mismatch at the feeding point, so, therefore, the antenna is NOT matched to its feeding objects. |

You seem a bit confused, Gareth. Are you feeling OK? |

You seem a bit confused, Gareth. Are you feeling OK? Actually this one seems to make sense, then I realized it was a self contradiction. He just proved that there has to be a mismatch in order for the unradiated wave to remain in the antenna, but if it remains in the antenna it must end up radiated... this just made my head explode! Maybe he is smarter than we think! -- Rick |

... I was going to post congratulations that no one replied to his nonsense, but then I found this thread... ![]() There is no nonsense in my threads. Now retired, I now have the time to muse upon and discuss those things in my electronics degree course from 40 years ago that did not add up*****. Certainly, those like Winnie-The-Pooh, the bears of very little brain, might think them to be nonsense, in which case I quote from Pope, "A little knowledge is a dangerous thing, Drink deep, or taste not the Pierian Spring" Bears of very little brain will mouth off in tirades of personal abuse, giving rise to the old adage of empty vessels making the most noise. ***** Even the acadaemics get it wrong, consider the arrant nonsense from Professor Maurice Hately, GM3HAT, with his crossed-field antennas ideas. |

Maybe he is smarter than we think! Gareth insists that he's unfailingly honest and I have never known him to admit he's wrong - misunderstood genius? |
