Koch Fractal Iterations Based T-Patch Antenna for Low Giga Hertz and Wireless Applications

Abstract

A compact size, low-weight, low-cost, Triple band antenna is intended for lower gigahertz applications. To make a Koch fractal antenna, a regular rectangular patch is modified with rectangular slots along the bottom edges on the left and right and a narrow triangular cut along the patch's intense top, left, and right sides. The Computer simulation technology (CST) Studio 2017 software simulator, which uses FDM (finite-difference methods) is used to study this structure. For low manufacturing costs, the suggested antenna is incredibly simple to combine with microwave circuitry. To design a triple-band micro strip antenna with frequency bands of 0.72 GHz, 3.89 GHz, and 5.45 GHz, Koch technique is suggested in this study. When the Koch fractal micro-strip antenna is used, the simulation results show that the antenna operates in tri - bands with return losses of -20.1 dB, -26.24 dB, and -11.79 dB at 0.72 GHz, 3.89 GHz, and 5.45 GHz respectively. The antenna is constructed on a Jeans substrate that has a permittivity with 1.71 and a thickness with 0.81 mm.
