The 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 and NEC viewer. From the simulated results, the proposed antenna has an operating frequency of 459 MHz and 1261 MHz and at these frequencies the voltage stand wave ratio (VSWR) less than from 2.
