Design and Analysis of Koch Snowflake Fractal Antenna Array

Abstract

This paper deals with the designing of antenna arrays of fractal geometry to obtain the desired performance like the compact size and multiband behavior. Single element antenna cannot cover different wireless standards. To achieve multiband and compactness, different array configurations of fractal geometries are needed. This paper describes the design approach and simulation of different array configurations of fractal geometries. This mainly focused on the Koch snowflake fractal geometry. The various array configurations are 1 x 2, 1 x 4 and 2 x 2. The elements of this antenna arrays are divided by a distance of 0.5λ. The proposed antenna arrays resonate at different frequencies and cover the different wireless communication systems such as Wi-Max, C-band applications, WLAN, X band for satellite communication. The effects of various parameters on the performance of the antenna array are analyzed using OpenEMS.
