Research ArticleOpen accessEvery word in the titleSmall Size and Dual Band of a Quadratic Koch Dipole Fractal Antenna DesignFawwaz J. Jibrael, Faez F. Shareef, Wafaa S. MummoThe performance and analysis of a small size, low profile and dual band quadratic Koch curve dipole antenna was introduced. The proposed antenna design, analysis and characterization had been performed using the method of moments (MoM) technique. The radiation characteristics, VSWR, reflection coefficient and input impedance of the proposed antenna were described and simulated using 4NEC2 software package, MATLAB v7.2 … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,116 accessesView PDFCite
