Design and development of the fractal based pentaband antenna is presented. The proposed antenna is fed by coplanar waveguide (CPW) – feed. Multiband operation along with miniaturization of the antenna is achieved by applying iteration techniques. Analysis of the designed antenna is done by High Frequency Structure Simulator software. The antenna has low profile and lightweight and easy to fabricate on an FR4 epoxy substrate with dielectric constant of 4.4 and thickness 1.6mm. The proposed antenna is compact with size 25×20mm2 and is useful for military, satellite, radar and WLAN applications.
