Design and Simulation of Rectangular Shape Sierpinski Carpet Fractal Antenna Array for Multi-Band Applications

Abstract

High data rates and better data quality are demanded features for modern communication. Multiband technology is used to increase the gain, bandwidth to a certain level. This paper describes in detail about on Sierpinski Carpet Fractal antenna array designed upto x-band frequency range by using Mitered Bend feed network up to the second iteration method in order to escalation the gain.  A 45°-meter bend in a micro strip line reduces a large reflection from the end of the line. Each iteration is scaled down to 1/3rd of the previous iteration. This carpet antenna is designed using High frequency structure simulator software on FR4 substrate with a dielectric constant of 4.4, and having thickness of 1.6mm.
