ABSTRACT
Antennas with rotational symmetry are a most complex variant of self-complementary antennas. They consist of several metal radiators and the same number of slots. Small wave impedances of new radiators should facilitate the task of matching and expanding the use of self-complementary antennas. The method of calculating a simple self-complementary antenna with a single metal radiator was proposed by Carrel. A step forward with respect to simple vertical antennas in the form of a flat metal dipole with a plate of angular width equal to a slot angular width was made as a result of creating the flat self-complementary antennas with rotation symmetry. The capacitance between the poles on both sides of the line consists of two pairs of different capacitances. The capacitances of the first pair are formed by flat cones with coincident axes. Capacitances of the second pair are capacitances between the cones with mutually perpendicular axes.
