Abstract :
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.
