A novel design of stair cased shaped fractal antenna for wireless applications

The paper exhibits a novel design of stair cased shaped fractal antenna for multiband applications. The antenna is designed on FR4 glass epoxy substrate with parameters like thickness 1.6mm, dielectric constant 4.4 and resonant frequency 3.8GHz. Proposed antenna is simulated and coaxial feed is used to analyze its performance. Maximum value of gain observed is 7.51dB. The HFSS version 13 software is used for designing and simulating the antenna. Designed antenna can be used for several wireless communication applications like S-band (2.67–2.87GHz), WiMAX (4.5–4.6 GHz), WiMAX (5.2–5.5 GHz), C-band (6.95–7.4 GHz) and X-band (8.6–8.65 GHz).
