Design & Simulation of Fractal Antenna for Wi-Max Operation

A metamaterial-based novel compact microstrip antenna is presented for Wi-Max applications. The antenna consists of a layer of metamaterial made by etching a crossed-shaped slots, on the the ground plane, respectively. The shunt inductance developed due to the patterned ground plane lead to the lefthanded behaviour of the metamaterial. The proposed antenna has a compact size of 45.4 × 31.6 × 1.6 and is fed by a 50 Ω microstrip line. Radiating patch is fractal antenna of star shape with 6mm side length. The impedance bandwidth (−10 dB) is from 3 GHz to more than 14 GHz with maximum radiation in the horizontal plane and tends towards a directional pattern as the frequency increases. Maximum gain 15.8533db obtained from fractal antenna.

Analysis and Simulation of Fractal Antenna for Mobile Wimax

The growing demand of wireless services requires the definition of new standards able to provide an increased degree of mobility for the end user and a higher speed of data transmission. Among emerging standards, one of the most promising is the IEEE 802.16 Wireless Metropolitan Area network Air Interface (generally called Wimax).In last few decade the miniaturization led antenna to be conformal, low profile, multi –band, hence Fractal antennas came into existence which due to its self-similar geometry takes less area and thus its low profile. This paper presents the design of Sierpinski carpet fractal antenna for three iterations. This antenna is designed using HFSS software on FR4 substrate having dielectric constant 4.4 and having fed 50 ohms micro-strip line and optimized to operate in multiple bands between 2 – 6 GHz.
