A Coaxial Probe Fed Multiband Hybrid Fractal Antenna for Wireless Applications

Hybrid Fractal multiband antenna is designed by combining Koch, Sierpinski gasket and Sierpinski carpet fractal geometries and its characteristics are investigated. The proposed antenna helps to achieve multiband behavior due to multiple resonance characteristics of fractal structure. Proposed hybrid fractal antenna has planar structure, compact size and suitable for wireless applications. IFS approach has been used to obtain the fractal structure using MATLAB and scripting method of HFSS simulator. Proposed antenna resonates at seven different frequencies 2.0909 GHz, 3.4545 GHz, 6.0909 GHz, 6.9091 GHz, 7.6364 GHz, 7.9091 GHz and 9.0000 GHz and hence generates seven frequency bands which can be utilized for wireless applications. It exhibits good radiation properties and has VSWR < 2 for all resonating frequencies
