A modified coaxial probe-fed Sierpinski fractal wideband and high gain antenna

This paper deals with modified Sierpinski fractal wideband antenna design. As research in the field of antenna design has already established, therefore it is exceptional that a novel approach is used over conventional antenna design methods to optimize the existing Sierpinski fractal antenna. The implemented antenna exhibits the broadband behaviour in the frequency bands of 12.2–13.4 GHz and 21–30 GHz in which it follows S11 ≤ −10 dB all through the frequency bands. The measured peak gains within the specified frequency bands vary from 8 to 22 dB. This high gain is achieved by employing the modifications to the initial Sierpinski geometry. The experimental and measured results of the modified coaxial probe fed Sierpinski fractal antenna are also presented. Experimental results are also validated.
