“…In this regard, various tunable band-notched UWB antennas have been reported over the last decade [14][15][16][17][18][19][20][21][22][23]. These UWB antennas actually implement the strategy of PIN diodes, shorting circuits, microelectromechanical switches (MEMS), stepper motors, and optically controlled switching techniques.…”

Abstract-The aim of this paper is to present a compact coplanar waveguide (CPW) fed switchable UWB antenna as an antenna filter with adjustable notched frequency bands. Novel miniaturized tunable resonators are also presented to achieve notched bands. The antenna is made tunable in notched frequency bands without any modification in the basic structure. These stopbands are made tunable just by varying values of the capacitors according to our desired applications. The antenna structure is very compact having overall dimensions of 24 × 30.5 mm 2 with partial ground plane. The proposed small size, variable, low cost and low weight antenna with good propagation characteristics will pave the way for UWB wireless communication applications.

In this paper, an ultra‐wideband (UWB) antenna with reconfigurable performance is proposed. The antenna consists of a U‐shaped radiation patch and a ground plane which is symmetric with the edge of the radiation patch. By using two open‐ended L‐shaped slots (OEL‐S) and one U‐shaped slot Defected Ground Structure, the dual notched bands at 3.5 GHz for WiMAX and 5.5 GHz for WLAN are obtained. Three switches are embedded in both L‐shaped and U‐shaped slots in order to achieve four switchable modes by switching them between ON and OFF states. There are three modes that the antenna can be switched in, which are dual, single and no band‐notched modes. The measured result illustrates that the operation frequency band is from 2.7 GHz to 12 GHz (VSWR < 2). Moreover, the conceptual circuit model and time‐domain characteristics of the antenna are also proposed to investigate the dual band‐notched performance. © 2017 Wiley Periodicals, Inc.

“…For minimizing the interference between narrow band and UWB systems, several types of printed antennas with reconfigurable band notch characteristics have also been proposed in the literature [9][10][11]. Some studies also highlight the use of p-i-n diode, varactor diode and RF micro-electromechanical system (MEMS) switches towards the design of reconfigurable printed antennas that are able to switch between available spectrums besides providing complete coverage within UWB and band-notched UWB of the single/dual tunable bands [9][10][11][12][13]. The use of switchable and tunable notch in UWB filter incorporating a total of sixteen p-i-n diodes connected in parallel has also been proposed by some researchers [14].…”

Abstract-This paper presents a novel frequency reconfigurable monopole antenna that has switchable notch characteristic at center frequency of 5.3 GHz. The proposed antenna consists of a defective ground structure (DGS) to enhance the impedance bandwidth from 3.17 to 13 GHz. The F-shaped parasitic element with three stubs (two vertical and one horizontal) are located on the back side of the radiating patch to achieve the band rejection characteristics from 4.9 GHz to 5.7 GHz. The metallic ground plane structure is connected or disconnected to the F-shaped parasitic element through stubs by means of p-i-n diodes. Experimental demonstration of applications of the proposed antenna structure as 5.3 GHz notched band ultra-wideband (UWB) antenna with all diodes in the OFF-state and as 5.3 GHz radiator for wireless local area network (WLAN) with all diodes in the ON-state is reported. In both the cases, good agreements between measured and simulated return losses, radiation patterns and realized gains are observed.
