Abstract: Wireless communication systems require antennas of multiband support,small design dimensions and higher gain. To provide size reduction and better impedance matching, geometrical interpreted fractal antenna is suitable. This allows the antenna to operate at different frequencies. To rise performances with respect to bandwidth, gain and multiband resonance, an array can fulfil the requirements. This paper shows the design and simulation of the Sierpinski Gasket array for multiband applications (4GHz to 8GHz, 8GHz to 12GHz) up to 4th iteration. The fractal geometry for patch antenna is selected due to low cross polarization radiation and ease of fabrication. Sierpinski gasket is known by the name, Sierpinski triangle having triangular slots using mid-point geometry of the triangle. This array makes use of micro strip feed where FR4 epoxy is used as the dielectric substrate. A low profile dielectric is used to get the radiation in maximum amount. This antenna finds its uses in satellite communications and transmissions,Wi-Fi. The simulation is carried out by using High Frequency Structure Simulator HFSS V13 software for the proposed antenna.
