A compact quasi-fractal monopole antenna for WLAN/WiMAX applications

Abstract

A novel CPW-fed compact quasi-fractal monopole antenna using Sierpinski triangle is proposed for WLAN /WiMAX applications. By using the L-system theory and a self-similar iteration design, the antenna is constructed with hexagons fractal patterns and slots. The proposal antenna covers all the 2.4/5.2/5.8 GHz WLAN operating bands and 2.5/3.5/5.5 GHz WiMAX operating bands. Also, good omni-directional radiation patterns and antenna gains over the operating bands have been obtained.
