“…In the literature, some other techniques have already been successfully demonstrated in achieving the UWB antenna with dual band-notch [25][26][27][28][29][30]. Thus, it is worthy comparing the proposed design of this work with the published designs reported in open literature.…”

“…Creating half-wavelength resonator slits on the antenna structure or on its associated ground plane is also one of the effective techniques to obtain such a realisation. For example, split ring resonator structures have been adopted in [27,28]; closed loop ring resonator have been used in [29]; In addition, two resonators of the mushroom-type EBG structure have also been demonstrated for such a purpose in [30].…”

“…The comparison of the simulated and measured peak VSWR at the central notched frequencies of the [26] Ref. [27] Peak VSWR Simulatedtwo notch bands are summarised and presented in Table 3. As can be seen, the proposed design shows reasonably superior performance than most of the existing studies using both simulation and measured data in terms of higher peak VSWR, equally higher rejection levels in two rejection bands.…”

Abstract-A printed monopole ultra wideband (UWB) antenna with frequency band-notched characteristics is proposed and investigated. The antenna consists of a half-disk shaped structure combined with an inverted isosceles trapezoid structure. To achieve the frequency band notched characteristics, an open-ended thin slit with a length of about one quarter guided wavelength is inserted on the radiator. Multiple slits can be employed to realize multiple frequency band notched characteristics. To validate the concept, two prototypes are designed, fabricated and tested. The first is a single band notched UWB antenna whereas the second is a dual band notched UWB antenna. The simulated and measured results of both antennas are presented shown a reasonable agreement between them. The results also confirm the proposed UWB antenna design can achieve superior dual band-notch performance at desired frequency bands.

“…SRRs and CSRRs have previously been used to design antennas with band notches. However, in most cases, the band notches are fixed, once the antenna is fabricated, and are always present in its frequency profile, as in [16] and [17]. Reconfigurable band notches are discussed in [18], where CSRRs are etched on the patch and electronic switches mounted across.…”

Abstract-The design of filter antennas with reconfigurable band stops is proposed. They are meant for employment in ultrawideband cognitive radio (UWB-CR) systems, where unlicensed users communicate using adaptive pulses that have nulls in the bands used by licensed users. Neural networks or circuits implementing the Parks-McClellan algorithm can generate such pulses. With filter antennas, reconfigurable bandstop filters are first designed, to induce adaptive nulls in UWB pulses, and are then integrated in the feed line of a UWB antenna. The advantages of this combination are discussed. The filters are based on split-ring resonators (SRRs) and complementary split-ring resonators (CSRRs). The relationship between the SRR and CSRR parameters and the stop band is also studied.

“…L-shaped slots [24], U-shaped slots [25], C-shaped slot [26], W-shaped slot [27] and H-shaped slot [28]. In [29,30], the authors have used split-ring resonators (SRR) in the antenna structure to create notch bands. It is shown in [31] that rejection bands can also be created by adding multiple U-shaped slots in a log periodic dipole antenna.…”

a b s t r a c tEmpirical results are presented for a novel miniature planar antenna that operates over a wide bandwidth (500 MHz to 3.05G Hz). The antenna consists of dual-square radiating patches separated by two narrow vertical stubs to reject interferences from GPS, Bluetooth and WiFi bands. Radiating patches and stubs are surrounded by a ground-plane conductor, and the antenna is fed through a common coplanar waveguide transmission line (CPW-TL). The two vertical stubs generate pass-band resonances enabling wideband operation across the following communications standards: cellular, APMS, JCDMA, GSM, DCS, PCS, KPCS, IMT-2000, WCDMA, UMTS and WiMAX. Embedded in the ground-plane conductor is an H-shaped dielectric slit, which has been rotated by 90°, whose function is to reject interferences from GPS, Bluetooth and WiFi bands. Measurements results confirm the antenna exhibits notched characteristics at frequency bands of GPS (1574.4-1576.4 MHz), Bluetooth (2402-2480 MHz) and WiFi (2412-2483.5 MHz). The impedance bandwidth of the antenna is 2.55G Hz for VSWR < 2, which corresponds to a fractional bandwidth of 143.66%. Measured results also confirm that the antenna radiates omnidirectionally in the E-plane with appreciable gain performance over its operating frequency range. The antenna has dimensions of 15 Â 15 Â 0.8 mm 3 .
