Abstract. The article presents the results of a research of an ultra-wideband fractal cube antenna. The fractal configuration of each edge complements the overall antenna structure in order to achieve ultra-wideband characteristics. Electrodynamic modeling of the antenna radiation characteristics has been conducted. A prototype of the antenna was made of a styrofoam. A copper film of a fractal structure with a thickness of 0.3 mm was applied on it. The total gain of the antenna varies between 2.4 – 7.6 dBi within the operating frequency band of 0.48 – 10.0 GHz. The antenna radiates an elliptically polarized field over the entire operating frequency range.
Key words: fractal antenna, spiral antenna, elliptical polarization.
