Abstract

A dual wideband CPW-fed slotted Koch snowflake fractal monopole, which is suitable for WLAN/WiMAX applications, is presented. The proposed antenna has been analyzed and designed with Ansoft HFSSTM v.11. Then an experimental prototype is fabricated and measured. It is compact with a total size of 41.5 mm × 27 mm × 1 mm (L×W×T). Results of simulation and measurement indicate that the proposed fractal monopole with a U-shaped slot has dual impedance bandwidths 2.35-4.25 GHz and 4.8-5.95 GHz, which covers WLAN bands (2.4/5.2/5.8GHz) and the WiMAX bands (2.5/3.5/5.5 GHz) respectively. In addition, good radiation performances such as omnidirectional and doughnut-shaped directivity and goodish gain over the operating bands have been obtained.
