Conclusions of the study in brief :

IX. CONCLUSION
CFA antennas have been exhaustively analyzed. From this
analysis, it is pointed out the following:
• A CFA antenna transmission line model has been proposed
and its equivalent network has been obtained. At
the same time, this model has been validated by means
of Moment Method simulations and some available experimental
data.
• From this approach, it can be seen three antenna working
possibilities according to the sign of the mutual conductance
G12.
• Two operating windows, for values of φ2 near 180◦ or 360◦, and some specific values of K permit having a
positive input power in each port.
• Antenna tuning has been obtained connecting the appropriated
coils including their merit factors.
• Antenna operation for each φ2-window has been compared
to a reference monopole of the same height and on
the same ground plane and top-loading conditions.
• It can be concluded that the disk presence has always a
deleterious effect, decreasing the antenna performance.
• The CFA performance is always a little worst than the
reference monopole in gain and bandwidth. The antenna
performance increases as either the antenna height or toploading
is increased, in the same way as for any standard
short monopole. Also, a simple monopole has a similar
or better performance with an easier tuning system.
• CFA antenna has the same radiation pattern and near
field distribution as any short monopole, then no Poynting
Vector Synthesis (PVS) can be seen close to the CFA
antenna.
• A CFA gain improvement is obtained installing it on
a building roof, in the same manner as for a standard
monopole, as it was pointed out since long time in
different parts of the frequency spectrum [35].
• It must be pointed out that moderated or high power
operations with short antennas does not mean they can
be installed in any place, but in conventionally isolated
areas as good engineering practice indicate for standard
LF and MF AM stations. Of course, this installation place
is matter of the Government Administration, due not only
to interference but to non ionized radiation levels too.

If you have made it this far, you might like to give your brain a proper workout and read the whole paper.
