Resumen/Abstract
This paper presents a compact micro-strip patch antenna for ultra wideband (UWB) applications using a Koch Snowflake fractal radiating antenna. The antenna supports two ultra widebands. For the lower band, a good impedance bandwidth of 6.55GHz has been achieved from 3.4892GHz to 10.0392GHz. While the upper band covers 5.4976GHz (from 10.9013GHz to 16.3989GHz). It is fed by a 50? micro-strip transmission line with an overall size of 30x27 mm. The simulation was performed by Computer Simulation Technology (CST) MICROWAVE STUDIO software, and compared with High Frequency Structural Simulator (HFSS) software. The results show that the proposed antenna has interesting characteristics for UWB applications.
