Compact-Size Fractal Antenna with Stable Radiation Properties for Wi-Fi and WiMAX Communications
( Amer T. Abed ),( Mandeep S. J. Singh ),( Mohammad T. Islam ) 한국인터넷정보학회 2018 KSII Transactions on Internet and Information Syst Vol.12 No.6
In this study, a novel fractal ring antenna with a compact size of 24×9×0.8 mm<sup>3</sup> was configured using three iterations. Low profile, circular polarization, and measured operating bands (4.5-6.5 GHz) meet specifications of the upper band used in Wi-Fi and WiMAX applications. The antenna featured, stable radiation properties, especially gain and efficiency, in the notched band (92%). In deep, the antenna impedance, reflection coefficients, surface current distribution and circular polarization for the three iterations had been studied to improve the process of antenna design and its radiation characteristics
