This paper considers the problem of forming of biconical antenna pattern, including the problem of retention of directional characteristics in the high part of frequency range. The method of improvement of the directional characteristics by filling the antenna aperture with inhomogeneous dielectric medium has been proposed. The distribution law of capacitivity in aperture has been chosen proceeding from postulate of geometrical optics. Law approximation has been received from the law of Lihtenekker for highly dispersed structure by decompounded complex three-dimensional configuration of one type of dielectric material with air gap. Possibility of manufacturing of this filling by means of 3D printing technology has been shown. Numerical simulation and experimental investigation of characteristics of biconical antenna have been performed, the reasonability of application of this method has been shown.
