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.

“…In [5], two rings are introduced to a Vivaldi antenna to obtain narrowband reconfiguration, however the gain that can be achieved is low, only up to 5.93 dBi. In [6], several ring resonators are introduced on the tapered slot to achieve one wide band and three narrow bands. The operating frequency can be switched between 1.10 GHz, 2.25 GHz and 3.10 GHz.…”

Abstract-This article proposes a frequency agile antenna whose operating frequency band can be switched. The design is based on a Vivaldi antenna. High-performance radio-frequency microelectromechanical system (RF-MEMS) switches are used to realize the 2.7 GHz and 3.9 GHz band switching. The low band starts from 2.33 GHz and works until 3.02 GHz and the high band ranges from 3.29 GHz up to 4.58 GHz. The average gains of the antenna at the low and high bands are 10.9 and 12.5 dBi, respectively. This high-gain frequency reconfigurable antenna could replace several narrowband antennas for reducing costs and space to support multiple communication systems, while maintaining good performance.

“…For these reasons, reconfigurability becomes another attractive method for designing a versatile UWB antenna combining characteristics of multiband and notch bands [18–23], which can be used as dual-notch band UWB antenna, single notch band UWB antenna, UWB antenna, or simply multiband antenna. Thus, a number of reconfigurable antennas have been proposed to meet one of these applications mentioned above [18, 20–23].…”

A coplanar waveguide (CPW)-fed circular slot antenna with wide tunable dual band-notched function and frequency reconfigurable characteristic is designed, and its performance is verified experimentally for ultra-wideband (UWB) communication applications. The dual band-notched function is achieved by using a T-shaped stepped impedance resonator (T-SIR) inserted inside the circular ring radiation patch and by etching a parallel stub loaded resonator (PSLR) in the CPW transmission line, while the wide tunable bands can be implemented by adjusting the dimensions of the T-SIR and the PSLR. The notch band reconfigurable characteristic is realized by integrating three switches into the T-SIR and the PSLR. The numerical and experimental results show that the proposed antenna has a wide bandwidth ranging from 2.7 GHz to 12 GHz with voltage standing wave ratio (VSWR) less than 2, except for the two notch bands operating at 3.8–5.9 GHz and 7.7–9.2 GHz, respectively. In addition, the proposed antenna has been optimized to a compact size and can provide omnidirectional radiation patterns, which are suitable for UWB communication applications.
