Design of Rhombus Shaped Fractal Antenna for WLAN and X-Band Applications

Abstract

Low profile features of microstrip antennas attract many researchers to investigate the performance of these antennas in various ways.Generation of multiband characteristic takes place when an antenna is introduced with some geometrical distortions i.e. fractal which is then used to increase data rates of communication system. Generally, an antenna tends to resonate at a single frequency but fractal antenna is a special type which has multiple resonances. Fabrication of miniaturized antennas have become possible due to fractal technology.This letter presents the design of Rhombus shaped fractal antenna using Sierpinski gasket structure.Two Sierpinski gasket structures has been combined, one in an inverted fashion which ultimately leads to a rhombus shape and the performance of second iteration antenna is studied.A 50ohms microstrip line is used to excite the patch.Analysis and Simulation of the proposed antenna has been done with the help of HFSS 13.0,an electromagnetic simulation software. The proposed antenna has been designed to resonate for LTE (long term evolution), WLAN and X-band Applications.
