Design and Performance Study of Sierpinski Fractal Based Patch Antennas for Multiband and Miniaturization Characteristics

Modern wireless communication systems demand for compact and miniaturised antennas which are capable of operating at multiple frequency bands. Cutting fractals on traditional geometry and using them as antennas for such applications have a wide scope of research. In this work, Sierpinski geometry based patch antenna is considered for multiband operation and miniaturisation of the radiating element. The characteristics of the fractal based antennas are investigated as a function of fractal iteration. The fabricated prototypes are used to validate the simulated results.
