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 microstrip line which consists of a 45 degrees bent which reduces reflection which is large  from the termination of the line. Each iteration is scaled down to 1/3rd of the previous reiteration. The HFSS software is used to design the carpet antenna with thickness of 1.6mm and dielectric constant of 4.4 on FR4 substrate.
