Bandwidth Enhancement of Microstrip Antenna Using Fractal Geometry for S-Band Applications

Abstract

The Sierpinski gasket fractal concept is used on a microstrip antenna in this paper. A self-similar property of fractal geometry is used, which is based on an iteration algorithm that reaches up to third iterations. It is simulated using the HFSS (High-Frequency Structure Simulator) software package version.15. A designed antenna is used to improve antenna performance, such as increasing bandwidth to 980 MHz and reducing the return loss from − 31.97 to − 23.4 dB. To excite the proposed antenna, a microstrip line feed is used. Up to 27% fractional bandwidth has been achieved in the antenna. This antenna can be used for a variety of wireless applications, including Marine radar and some communication satellites such as (Wireless LAN, Bluetooth, microwave devices/communications, and cell phone), as well as the lower portion of C-band.

A New Approach for Calculation of Metamaterial Printed Fractal Antenna Using Galerkin’s Method

“…Various fractal structures, such as Cantor Bar, Koch, Tree, Minkowski, and Hilbert, were used for designing multiband antennas [4][5][6].…”
