A innovative geometry of fractal microstrip antenna has proposed which can be used for various multiband applications. This hexagonal fractal antenna structure has designed to produce multiband characteristics or to achieve miniaturizations. Multiple hexagons of the proposed geometry of an antenna are interconnected to maintain conductivity and to preserve electrical self-similarity. The hexagonal fractal antenna is implemented in the corner fed dipole configuration with overlapping vertices to preserve the electrical self-similarity paramount in multiband design. Coaxial feeding has used to make the design of antenna versatile in term of impedance matching. This antenna has designed up to f iteration through miniaturization procedure. Proper and improved results has observed at fourth iterations of the antenna design.
