Design of H-fractal antenna for multiband applications

This paper presents the design of an H-fractal antenna for multi band applications. Introducing fractal concept, the H-shaped microstrip antenna is designed. Using space-filling property of fractal geometry, the size of antenna is reduced. Seven iterations of H- fractal multi-band antenna are arranged and examined.The H- fractal planar antenna is fabricated on an FR4 substrate with a 1.6 mm thickness. The H- fractal planar antenna is fabricated on an FR4 substrate with a 1.6 mm thickness. The design is analyzed using HFSS v15 which is based on Finite Element Method (FEM).The antenna operates at resonant frequencies of 2.45/5.5GHz WLAN applications. Reflection coefficients |S11| and radiation properties of the proposed H–fractal antenna make it suitable for a variety of wireless application
