I have seen other designs that seem related, like the floating sleeve dipole.
It's a serious design, I am working with it at 2.4G in Sonnet. I have the main antenna on top of the PCB, and of course the area on the other side of the PCB is "free".
So, I wondered if there's something useful to...
Familiar with those, this is a free floating element that is not connected to the DE but may be identical to it, just very very close, so that it does not act as a reflector or director at this frequency.
I'm familiar with using parasitic elements out away from the driven element as directors or reflectors.
I have seen an antenna that used a parasitic element close in to the driven element. For example if the DE were 1/8" wire then the PE would also be 1/8" wire spaced maybe 1/8" away.
The DE...
