Summary:
A multiband cpw-fed slot antenna with fractal slit in rectangular stub is proposed. The conventional wideband slot antenna was modified by inserting the fractal silts in both side of the rectangular stub. The fractal silts can generate multi-notch frequency that affects to change the wideband performance antenna to the multiband performance antenna suitable for applications in wireless communication systems. In this paper, the fractal Hilbert slit with the 0 and 1st iterations has been employed. The comparisons between simulation and measured results are agree well, resulting from 1st iteration slit. The S11 bandwidths of each band include 25.12%, 35.32%, and 17.18%. Additionally, the presented antenna can operate and cover the applications of DCS1800, WCDMA 2100, Worldwide Interoperability for Microwave Access (WiMAX), Wireless Local Area Network (WLAN IEEE 802.11a/n), and IMT advance system (4G mobile communication system).
