Hi Big M.

This is my favorite coil setup.

any patents on such coil?

Try this one:


#2,292,182
A radio receiving antenna. (Fig. 4 is the most useful.)

#4,644,366
Strange.  Think of a vertical spring coil inside a Faraday cage(Figs. 6 & 7).




#4,080,585
Unusual.  A printed circuit coil on two sides of a board.




#3,428,886
New and unusual toroids.  Might be used in a Joule Thief.




#3,273,098
The concept is used in impedance matching systems.




#3,237,220
Similar to #3,273,098.   Just make the wires a lot longer.




#2,971,173
An RF transformer with or without(?) a ferrite core?




#2,242,023
Think of the outline of an Iron Cross or possibly a Roman Catholic cross with extra cross pieces, all wired in series.





#1,586,144
Fig. 1 is the most useful.  For naturally large systems.




#243,180
Fig. 4 is a Caduceus coil.

#4,679,046
Fig. 3 suggests a use in electromagnetic spacecraft propulsion drives.




#2,897,497
Obviously a Yagi-style TV antenna.  Marconi invented the original design, which should be listed on the thread.




#2,208,413
Radio beacon antenna with air core coils along its length.

#4,978,966
Fig. 10 has 3 ferrite coils in parallel as a flexible car radio antenna.



#1,495,537
This can be wired as an opposing bifilar coil.

ok

All is fine but give us patent which clearly states radiant energy and/or patent explaining multiple receivers joined with energy gain which may be above unity
