Fractal-Based Patch Antenna Design for Multi-band Applications
A \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$1\times 3$$\end{document} linear Koch Snowflake antenna array is proposed for multi-band applications. The Koch array has a gain of 1.2 dB, 4.38 dB, and 5.22 dB at 5.4 GHz, 7.7 GHz, and 9.8 GHz, respectively. The number of resonant frequency of the Koch fractal increases as the number of iteration increases. The design and simulation of the Koch antenna were done in AnSoft HFSS and MATLAB. The antenna parameters, such as peak gain, bandwidth, and return loss, are analysed and presented for different iterations. The return loss obtained for all Koch antennas studied is well below −10 dB which shows good radiation characteristics. The third iteration Koch fractal antenna was fabricated using FR4 substrate and tested using Vector Network Analyser. The good agreement between the simulated and measured values validates the proposed design and satisfies the requirements for multi-band applications. Based on these results, the presented fractal-based patch antenna system can be considered as a best candidate for multi-band wireless systems.
