Pattern lobes and beam widths of a novel fractal antenna

Abstract

Important element of any transceiving wireless devices are antennas, form of which influences on the quality of transmission and reception of information. These systems require multirange, broadband antennas that are small in size. In this paper experimental results on the determination of the radiation pattern of a novel small-size fractal antenna of based on an anisotropic curve are described. The fractal structures on the basis of which the antennas are built have self-similarity properties and are characterized by scaling effects. All this provides unique in comparison with standard types of antennas characteristics of uniformity of the radiation pattern over a wide range of frequencies while minimizing (5-10 times) the linear dimensions of the antennas, which is especially important for long-distance communication bands. The antenna beamwidth is the angular width expressed in degrees which is measured on the major lobe of the radiation pattern of an antenna. We present the experimental results for determining the width of the prototype pattern of the anisotropic fractal antenna. We used the software and hardware complex that we created. An anisotropic fractal antenna was used as the radiating antenna.
