Antenna with hexagonal fractal geometry using ultra wide band pattern is been discussed in this paper. The proposed antenna is fed with co-axial line and its structure depends on hexagonal fractal geometry wherever resonance frequency of antenna is a lowered using iteration technique, which is the repetition of motif over two or more scale sizes. CST microwave studio suite has completed the analysis of this Ultra Wide Band (UWB) pattern. This fractal antenna is low height and width, light weight and simple to fabricate. Proposed antenna possesses multiband and broadband characteristics.
