Synthesis of Quasi-Fractal Hemispherical Dielectric Resonator Antennas

The paper considers the models quasi-fractal dielectric resonator antenna (DRA) based on a hemispherical. Thus, the influence of the depth of the overlap of the constituent elements in the spatial-frequency characteristics DRA. The interaction of the antennas of non-Euclidean geometry with radio waves is described difficult. It is therefore advisable to perform the synthesis of these antennas by mathematical modelling using the Ansoft HFSS package. To simplify the analysis of the characteristics of the antennas, their arrangement is limited geometrical structure, which has five elements on one horizontal surface. Evaluation and comparison of antennas held by the following characteristics: amplitude-frequency response, beam pattern and voltage standing wave ratio.
