A reconfigurable wide slot antenna integrated with sirs for UWB/multiband communication applications

Abstract

Abstract A reconfigurable wide slot antenna integrated with stepped impedance resonators (SIRs) and ideal switches for ultra‐wideband (UWB) and multiband communication applications is proposed. The proposed reconfigurable antenna can be used as a UWB antenna, a dual notch‐band UWB antenna, and multiband antennas. The dual notch‐band functions are obtained by using two stepped impedance stub‐loaded SIRs. The reconfigurable characteristics are achieved by using two ideal switches on SIRs. The measurement and simulation results show that the proposed reconfigurable antenna has good switchable characteristics and dual notch‐band functions. The designed reconfigurable antenna is suitable for future multimode wireless communications systems. © 2012 Wiley Periodicals, Inc.
