On the design of 2×2 MIMO fractal antenna array for C band applications

Abstract

A 2×2 MIMO planar fractal antenna array using Sierpinski gasket along with microstrip feed line has been investigated. Different configurations of antenna array has been studied. The optimized unit element used in array is further modified geometrically by corner rounding and cut in feed to improve its performance including gain. Proposed fractal array antenna resonates at 4.19 GHz and 7.86 GHz lies in C band and simulated using High frequency structure simulator. Such an attempt has been rarely reported in the literature. Simulated reflection coefficient shows that Proposed antenna works in C band frequency range for various applications and results are quite promising.
