“…In some cases, these narrow-band signals may interference with UWB systems or vice versa. To suppress these unwanted potential interferences, the traditional method is to add narrow-band band-stop filters at the end of the antenna or in the devices, which increases the complexity and cost of the devices [5, 6]. To design a UWB antenna with a filtering characteristic, cutting slots may be one of the simple, effective, and inexpensive methods.…”

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.

“…The proposed antenna is fabricated on a FR4 substrate with relative permittivity of 4.4, thickness of 1.6mm and a loss tangent of 0.02. The dimension of this antenna is 30 × 41 mm 2 . The antenna provides the extra Bluetooth band operation due to the T-shaped strip added on the radiation patch.…”

“…Several types of monopole antennas have been proposed for UWB and band-notched applications [2][3][4][5][6][7][8]. A recently reported antenna has been designed by etching a rectangle slot in the CPW ground [2], by embedding a parasitic strip inside the polygon slot and an isolated slit employed in the bevelled T-stub [3], and use the two L-shaped quarterwaveguide resonators coupled to the ground plane with two shorting tracks at the sides of the antenna [8] to get the single band-notched characteristic. In [4], the dual notched bands were formed by embedding a pair of г-shaped stubs in the radiation patch and a modified G-slot defected ground structure in the feeding line.…”

“…In the conventional design, band-stop filters are added at the end of the antennas or the devices. Thereby, the cost is increased and the size of the antenna is getting large [8]. Designing a UWB antenna with one or several rejection filter characteristics is a hot topic in recent years.…”

“…For these reasons, UWB communication has attracted much attention in recent years. A UWB antenna is an important part in UWB wireless communication, and a lot of UWB antennas have been proposed for UWB applications [2][3][4][5][6][7][8][9][10][11][12][13][14]. However, most of the previous UWB antennas have large size and complex structures.…”

Abstract-A compact reconfigurable antenna integrated with stepped impedance stub (SIS) loaded stepped impedance resonator (SIR) and SIS loaded hexagon stepped impedance resonator (HSIR) for ultra wideband (UWB) applications is proposed in this paper. The reconfigurable UWB antenna can work as a UWB antenna and a dual notch band UWB antenna by controlling the switches ON and OFF. The proposed two notch bands are obtained by embedding a SIS-HSIR on hexagon radiation patch and a SIS-SIR on coplanar waveguide (CPW) excitation line. The reconfigurable characteristic is achieved by means of two ideal switches. The proposed reconfigurable antenna has been designed, fabricated and measured. The experimental results show that the proposed reconfigurable antenna has a multi-mode function and good omni-directional characteristics.
