Abstract

In this paper, Koch Fractal Antenna (KFA) focuses on the design strategy with resonant frequency of 1.35 GHz\nthat is capable to hold the multiband behavior. The fabrication is done by using FR4 epoxy material for substrate whose\nrelative permittivity 4.4 and the height of the substrate 1.6 mm. The dimensions of the proposed KFA antenna are 65 mm x\n65 mm which is square in shape. The Koch fractal geometry is applied up to 3rd iteration in order to enhance the performance\nof the antenna. In this work, microstrip line feed is used to fed the antenna. The different antenna parameters such as gain,\nreturn loss, VSWR and radiation pattern are evaluated and analyzed. The High Frequency Structure Simulator (HFSS)\nsoftware is used for analysis and simulation of the proposed KFA. This antenna works for multiband applications.
