| Can anyone show some math? Something pointing to f1(Gmax) = f2(S11min)? Where f1 != f2, but it hightlights how they are tied together?
How about this: G=4pi*A,e/lambda^2, where Lambda=c/f1 Zi ... |

| Recently learned that f(Gmax) is (usually) not always same as f(S11).
One example: ½ ? dipole where at Gmax, Z=72+j ~200, so S11 not lowest. Any othere examples? |
