摘要：
This paper proposes a novel design of a multiband fractal antenna of irregular shape using two-dimensional fractal clusters. The algorithm of generating fully reproducible fractal clusters is developed. The multiband behavior of the fractal-cluster based antennas is studied by means of numerical analysis. In comparison to regular-shaped fractal antennas more frequency bands and better matching are achieved. The spatial-frequency antenna characteristics are studied under feeding point displacements. As shown by numerical results, small displacements of feeding point allow to control the radiation pattern in certain frequency bands. The larger feeding point displacements are demonstrated to shift antenna frequency bands.
