Comparison of Radiation Characteristics of Fractal Arrays with Random and Periodic Arrays

R. Vikas

Abstract: In recent years, Antenna design has become one of the important consideration in communication technology. Different antenna designs serve different purposes basing on their performance characteristics, physical design constraints and radiation characteristics. This paper discusses the concept of fractal geometry and correlates to antenna theory. This paper aims to investigate how a random array antenna radiation characteristics can be improved by the choice of fractal geometry of Sierpinski gasket over random and periodic array antenna. Matlab code is used to generate antenna geometry and also its radiation pattern along with its array factor curves
