Meander line antennas, including "fractals", share the same properties

conductor current. The latter can result in poor efficiency due to I^2 *

worse than others, depending on how the meander and other methods are
implemented. It's just one of the techniques which antenna designers
have in their bag of techniques to use.

Hello, and you make some good points, Roy. (I always pay close attention
to many of Steve Best's IEEE papers on antennas). While I've not analyzed
or experimented with antennas based upon fractal patterns I have always
wondered whether broadband performance could be achieved since fractal
patterns would repeat with electrical (frequency) scaling. Granted, these
patterns unlike, say a logarithmic spiral, would only repeat at discrete
values. Your comment above indicates this is not the case, however.
Sincerely, and 73s from N4GGO,
