Antennas with rotational symmetry

Methods of calculating flat and volume self-complementary and similar to them antennas consisting of a several metal and slot radiators are developed and described. These methods allow to define a mutual partial capacitances per unit length between the single radiators and groups of radiators, connected with each other, and a wave impedance of each antenna's variant. Flat vertical antennas, antennas located on the sides of the pyramid, conic and parabolic antennas are considered and analyzed. Recommendations on ways permitting to improve the antenna matching are presented.
