Antenna synthesis based on fractal approach and DRA technologies

The paper presents the results of the study combined antennas developed on the basis of dielectric resonator elements and a fractal approach. This approach allows to achieve a broadband and multi-band antenna systems. As a basic structure is considered, composed of a recursive tree and passive dielectric resonators. To simplify the analysis of the characteristics of the proposed antennas, their arrangement is limited by the fractal on the level of the first three iterations, and the number of dielectric resonators does not exceed four. Due to the complexity of describing the interaction of the antennas of non-Euclidean geometry with radio waves for their synthesis and analysis selected methods for the numerical simulation. An evaluation of the spatial-frequency characteristics of the designed antenna solutions used indicators such as return loss, beam pattern and voltage standing wave ratio.
