A Circular Fractal Antenna Array

Abstract

In this paper, different arrays of the circular fractal antenna are analyzed. The various array design configurations are 1 $\times 2,1\times 4,2\times 2$ and $2\times 4$. The substrate used is FR4 whose dimension is varied according to the array configurations. A $\pmb{50}\Omega$ microstrip feed line is used to excite the antenna for all the configurations. The antenna shows stable radiation pattern and have good $S_{11}$ characteristics. All the analysis is done in HFSS 2014.
