ABSTRACT

The complementarity principle comes from to an interconnection between scattering properties of the metal and slot radiators of the same shape and dimensions. Performed analysis shows that the choice of the surface for the placement of the self-complementary radiated structures is not random. The conical problem exemplifies the three-dimensional problem of calculating the electric field of charged bodies. Increase in the length of such antenna arms allows use of the antenna of the same height as the height of flat self-complementary radiator to improve the electrical characteristics or, at the same characteristics, to reduce its height. An electric radiator consists of two flat metal cones, located along the upper and lower pyramid edges. The magnetic radiator consists of two slots located along the side edges. The simple shape of an antenna on pyramid sides in comparison with the forms of antennas located on the surfaces of rotation facilitates and simplifies the construction of large antennas for the medium-wave band.
