Dielectric resonator antenna based on fudgeflake geometry

Fractal shaped antennas exhibit some interesting features that stem from their inherent geometrical properties. The self-similarity of certain fractal structures results in a multiband behavior of self-similar fractal antennas and frequency-selective surfaces. From the other point of view, high convoluted shape and space-filling properties of certain fractals allow to reduce volume occupied by a resonant element. Although complex objects with similar properties of the fractals could be defined, the use of fractal geometries has the advantage that irregular complex objects can be described in a well-defined geometrical framework. In this paper, the performance of a new type of dielectric resonator antenna based on fudgeflake fractal geometry with different iteration levels has been investigated numerically
