A CPW-fed wide-slot antenna with reconfigurable notch bands for UWB and multi-band communication applications

In this article, we present a compact wide-slot antenna with reconfigurable notch bands, for ultra-wideband (UWB) and multiband communication applications. The dual band-notch characteristics are realized by using three open-ended stubs inserted into the fork-like radiating element, and the reconfigurable characteristics are achieved by integrating ideal switches in the stubs. By controlling the ON/OFF states of the ideal switches, the proposed antenna can function either as a UWB antenna with two notch-bands, or a single notch-band UWB antenna, or even a multiband antenna. The simulation and measurement results show that the proposed antenna is suitable for UWB as well as multiband communication systems. (c) 2013 Wiley Periodicals, Inc.
