Comparison of the Radiation Characteristics of Triangular and Quadratic Koch Fractal Dipole Wire Antennas

Abstract

In this paper, a small size, low profile and multiband triangular and quadratic Koch curve dipole antenna are presented. The proposed antennas design, analysis and characterization had been performed using the method of moments (MoM). The designed antennas have operating frequencies of 603MHz, and 1789MHz for triangular Koch dipole antenna and 460MHz and 1262MHz for quadratic Koch dipole antenna. The radiation characteristics, reflection coefficients, VSWR, gain, and input impedance of the proposed antennas are described and simulated using the 4NEC2 software package.
