Three feeding circuits for circular
polarization antenna: circuit with one feeding element, circuit with two feeding
elements and lossless power divider, circuit with two feeding elements and
balanced power divider are considered. Feeding circuits and antennas on their
base are compared by three indexes of quality: operating frequency range,
minimal gain in the range, minimal axial ratio in the range. Methods of
multi-criteria optimization are used for antennas comparison. Pareto pluralities
in space of quality indexes for all the considered antennas are obtained.
Equivalence of circuit with one feeding element and circuit with two feeding
elements and lossless power divider is demonstrated.
