Dipole Antenna with Fractal Koch Curve Geometry for Multiple Frequency Applications


This paper presents the analysis, simulation, and design of a small size, low profile, multi-band third iteration quadratic Koch fractal dipole antenna. The proposed antenna design, analysis and characterization have been performed using the method of moments (MoM) technique. The new designed antenna has operating frequencies of 960 MHz, 1514 MHz, 2914 MHz, 3274 MHz, and 3480 MHz with acceptable bandwidth, which has useful applications in wireless communication systems, and at these frequencies the proposed antenna has reflection coefficient < -10 dB (vswr < 2). The radiation characteristics, vswr, gain, radiation efficiency, and reflection coefficient of the proposed antenna are described and simulated using 4nec2 software package.
