And, therefore, by the reciprocity characteristic, the short antenna is an inefficient radiator? No, not at all. If the kind of reciprocity to which you refer were true, then the receiving antenna would capture ALL the power radiated. That obviously cannot be, so I think your idea of reciprocity may be a bit flawed. His whole grasp of antenna theory is flawed. He was trying to (indirectly) argue the other day via his his interpretation of Maxwell's Equations you could generate an EM wave by waving a magnet about. When corrected, he introduced another variation. |
