Design and Analysis of Microstrip Sierpinski Fractal Antenna for Wireless application

Abstract

This paper describes a novel design for a microstrip fractal antenna based on the Sierpinski triangle shape. It is built on a FR4 substrate and operates in the 5.5 GHz frequency range. The proposed antenna is designed and validated using ANSYS Electronic Desktop's High Frequency Structure Simulator (HFSS). The simulated results show good performance in terms of radiation pattern, gain and input impedance. This proposed antenna can be widely used in wireless communication equipment that is progressing towards miniaturization and high frequency. The antenna designed gives a return loss of -29 dB at 5.53GHz. It has a gain of 0.85 dB and directivity of 1.8dB.
