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. © 2013 Wiley Periodicals, Inc.
