ANALYSIS OF NOVEL FRACTAL OPTICAL ANTENNA ARRAYS - A CONCEPTUAL APPROACH

This paper presents the analysis of novelistic fractal optical antenna arrays in a conceptual manner. Fractal antennas are array antennas with converging and diverging growth of basic element or elements for multi-wideband capturing of the electromagnetic waves. Most of these antennas relay on two components for their characteristics. First one is the basic stage shape and second one is the number of stages of growth. For computing the direction of radiation the well-defined fractal array manifold and a good estimate of the covariance matrix of the fractal array response is needed.
