Multiband Fractal Patch Antenna: Modification and Miniaturization of Sierpinski Gasket

The evolution of the current systems using fourth generation technology is based on the key idea of interoperability. In future systems, a single terminal should be capable of performing all the functions - anywhere, at any moment and in any interface, resulting in a convergence of services. This paper presents the design and simulation of a novel miniaturized microstrip fractal patch antenna which resonates at 3.1GHz, 3.8GHz, 5.6GHz, 6.9GHz and 7.7GHz. The size of the antenna is compacted by 30 % in comparison with a regular Sierpinski gasket antenna. All the simulations have been performed using ANSYS HFSS software. The obtained results have also been validated using Keysight N9915A network analyzer. The simulated and experimental results are found to be in good agreement.
