Dear LF group,
I have been looking for some information about the polarization of small
loops, but no success.
For full-size loops things are quite clear, a loop can be polarized
horizontal or vertical depending on the feeding point.
What about small loops ?
I found several descriptions of small transmitting loops close to ground
and there loops were fed at different places (center horizontal side, at
the edges). Polarization seems to be vertical in all cases.
And what about a small loop is free space ? Current distribution is uniform
over the entire loop, regardless of the feeding point. So one would expect
always the same polarization (but which one ?). Unless also the voltage
distribution plays a role.
Anyone who can point me to the right theory and/or has experience with
feeding small loops at different points ?
Thanks in advance,
Rik ON7YD
