Bandwidth Analysis of Microstrip Antenna With Fractal Design for 2.4 GHZ Wireless Applications

Abstract

The Microstrip antenna incorporated with the fractal component is presented with the antenna parameter analysis through the high-frequency simulation results. The main intention of this work is to analyze the bandwidth parameter of the antenna in terms of an increasing number of iterations of fractal components. This work comprises three iterations of Koch Snowflake antenna design, which are simulated using High Frequency Structure Simulator (HFSS). In addition, the significances of all iterations are highlighted, based on the simulated antenna parameters such as return loss, gain, VSWR and radiation pattern. The design starts with an initial triangular antenna resonated at 2.4 GHz which is suitable for Wireless Local Area (WLAN) applications. The substrate FR4 is being used with the dielectric constant
