Design of Sierpinski Gasket Fractal Antenna Using Proximity Coupled Feed Mechanism for Multiband Applications
In this paper, the design of Sierpinski Gasket fractal antenna using proximity coupled feed for multiband applications is presented. Certain properties of designed antenna structure like return loss and directivity are analyzed and simulated using 3D electromagnetic simulator CST MWS 14.0. The proposed antenna is designed on FR-4 lossy substrate with thickness 1.6mm and relativity permittivity 4.4. The proposed antenna has resulted after the successful combination of first, second and third iterations. Simulated results show that from second iteration onwards, the antenna starts showing multiband behavior at different frequency bands.
