Modified Sierpinski fractal patch antenna

The Fractal geometries have unique properties such as space filling and self similarity. For achieving the desired miniaturization, multi-band and wideband properties the fractal geometries have been exploited in antenna designing. The paper proposes a novel geometry called as modified Sierpinski fractal for better performance as compared to the traditional existing Sierpinski geometry. The proposed modified Sierpinski has been compared with the existing Sierpinski for the microstrip fractal patch antenna. The modified Sierpinski has been compared on a dielectric substrate of FR-4 lossy with a dielectric constant of ε
r
=4.3. Both the geometries have been compared up to fourth iteration. The calculations and comparisons of return loss and radiation patterns have been done and shown in the communication.
