EVALUATION OF SPACE-FREQUENCY CHARACTERISTICS OF A QUASI-FRACTAL DRA BASED ON A CUBE AND TRUNCATED PYRAMIDE

Abstract

In paper considered, models of quasi-fractal dielectric resonator antennas (DRA) based on a cube and truncated pyramid. Ansoft HFSS package used for their synthesis. For the purpose of evaluation influence of antenna geometry on its space-frequency characteristics, variants for DRA composition defined which differ in location of elements and depth of their overlap. Analysis of the results performed based on comparison frequency response, radiation pattern and standing wave ratio.

Keywords: antenna, frequency response, standing wave ratio Ansoft HFSS, radiation pattern, DRA, fractal.
