Design and Simulation of A Compound Fractal Antenna For Multiband Applications

The traditional Sierpinski gasket monopole antenna is well known for its multiband behavior. Compound fractal antennas have the potential to provide multi-band solution through the property of self similarity that the fractal shape poses. Using a combination of structures we can achieve much better bandwidth than the conventional and traditional fractal antennas. In this paper, a multi-band antenna based on new compound fractal geometry is presented, where the radiating patch is designed in fractal configuration. The aim is to design a multiband antenna with a circular slot inscribed in a triangular patch and to study the effect of iterations on the antenna characteristics. The design is simulated using HFSS software. It is a compact design, fabricated on FR-4 substrate. Here coaxial feeding technique is used to excite the patch. The designed antenna is studied for return loss and bandwidth.
