Abstract
In modern wireless communication systems, antennas that are robust, mechanically simple and yet compact are increasing in demand. Likewise, antenna systems with multiband properties are greatly desired over the traditional types. This has stimulated antenna investigation in various fields; one among them being usage of the fractal shaped antenna elements. Fractal geometries radiate electromagnetic energy effectively and have features that have an added advantage over conventional antennas. In this paper a Multiband Sierpinski Carpet fractal antenna is constructed for four iterations at an operating frequency of 2.40 GHz. ANSYS HFSS firmware has been utilized for simulation and analysis. The antenna parameters; VSWR, Gain, Directivity and Radiation Efficiency have been attained. In addition, improvement in Return Loss property was observed with increase in iterations. But this improvement begins to disappear after the third iteration.
