Analysis Of The Patch Antenna Based On The Sierpinski Fractal

There has been an ever growing demand for antenna designs that possesses compact size, low profile and multiband features. Recently the possibility of developing antenna designs that exploit in some way the properties of fractals to achieve these goals, at least in part, has attracted a lot of attention. Fractal antennas have useful applications in cellular telephone and microwave communications. Video conferencing, streaming video are main applications that require high data rates to have high bandwidth. But as size of antenna reduces bandwidth support also reduces. So it is required to have small size with high bandwidth. Fractal antennas are proposed in literature for different applications as it is compact and also has good bandwidth. Fractals found widespread use in many branches of science and engineering in a relatively short time. Recent progress in the study of fractal antennas suggests some attractive solutions for using a single small antenna operating in several frequency bands. The term fractal, which means broken or irregular fragments, was originally given by Mandelbrot to describe a family of complex shapes that possess an inherent self-similarity in their geometrical structure. In this paper various types of fractal antennas like sierpinski gasket, Koch and hexagonal are studied and their capabilities in SHF and UHF band are discussed.
