Methodology of improvement of directional properties of aperture reception elements of direction-finding array

In this paper the single biconical ultra-wideband reception device which is a part of directional-finding array is considered. Directional characteristics and matching of this device well-known and this characteristics can be improvement in several ways, for example, by means of the dielectric lens. However, use of classical lens essentially increments the terminating dimension of a device and all system. In this paper methods of transformation of the shape of a radiation pattern by means of the different dielectric insert in interior volume of receptions device are described. Directional characteristics and matching of a reception element will be defined by shape and dielectric properties of an insert.
