“…Addition of parasitic elements near the printed antennas and use of defected ground structure or electromagnetic band gap had also been reported to achieve notched frequency band [24][25][26][27][28][29][30][31][32][33]. Introduction of open-end slit to the antenna structure and addition of a tuning stub within the antenna structure or the ground plane were also reported to create and control notched band/s [34][35][36][37][38][39]. For example, in [34], an ultrawideband rectangular aperture antenna was presented.…”

“…Despite of having fairly compact dimension, the proposed antenna completely rejected the entire 4.85-6.04 GHz frequency band, though the desired notched-band for WLAN is 5.15-5.825 GHz. So, any useful information contained in the frequency band of 4.85-5.14 GHz and 5.826-6.04 GHz will also be lost resulting in [39]. Four Lshaped slots were symmetrically etched on the substructure to obtain a notched frequency.…”

Abstract-In this paper, a compact ultra-wideband microstrip-fed annular ring antenna with band notch characteristics for wireless local area network (WLAN) and dedicated short-range communication (DSRC) is proposed. The proposed antenna comprises an annular ring patch and a partial ground plane with a rectangular slot. The notched frequency band is achieved by etching a partial annular slot in the lower portion of the ring radiator. The centre frequency and bandwidth of the notched band can be controlled by adjusting the width and position of the annular slot. Measured results show that the proposed antenna achieved an impedance bandwidth of 3-10.6 GHz with a notched frequency band centred at 5.5 GHz. Compared to the recently reported band-notched UWB antennas, the proposed antenna has a simple configuration to realize the band notch characteristics to mitigate the possible interference between UWB and existing WLAN & DSRC systems. Furthermore, a symmetric radiation patterns, satisfactory gain and good time domain behaviour except at the notched frequency band makes the proposed antenna a suitable candidate for practical UWB applications.

<span>This paper proposed an UWB antenna with triple reconfigurable notch filters. By presenting there U-shaped coppers in the design, the potential triple interference in UWB applications can be rejected. Six PIN diodes are putted on the coppers to represent the OFF and ON tunable status in order to add reconfigurable characteristics to the UWB antenna. By using this ON and OFF tunable method, the current distribution of the proposed design changes and enables the antenna to have eight operation modes. The results prove that the proposed design can operate over the entire UWB frequency range (3.1 GHz to 10.6 GHz) and can filter out the target signals from the WLAN upper band (5.725 to 5.825 GHz), WLAN lower band (5.15 to 5.35 GHz) and X band frequency system (7.9 to 8.4 GHz) in one of the tunable configurations.</span>

“…Most researchers tend to use monopole antennas to achieve UWB response due to their attractive features such as easy manufacture, low cost, omnidirectional radiation high data rate and wide frequency bandwidth which is suitable for UWB applications [4]. However, UWB technology is facing interference problem with other narrowband systems such as WiMAX (3.3-3.7 GHz), HiperLAN2 (5.47-5.725 GHz) and WLAN (5.15-5.35 GHz, 5.725-5.825 GHz) [5][6][7]. Thus, a microwave bandstop filter is integrated into the UWB system to remove unwanted signals and reduce the possible interference.…”

Abstract-This study presents a novel technique for designing an ultra-wideband (UWB) filteringantenna with dual sharp band notches. This design is composed of a modified monopole antenna integrated with resonant structures. The monopole antenna is modified using microstrip transition between the feedline and the patch. In addition, block with a triangle-shaped slot is loaded on each side of the ordinary circular patch to produce wide bandwidth with better return loss and higher frequency skirt selectivity. The resonant structures are constructed using two double split ring resonators (DSRR) loaded above the ground plane of the antenna to produce dual band notches and filter out WiMAX (3.3-3.7 GHz) and HiperLAN2 (5.4-5.7 GHz) frequencies. The band notch position is controlled by varying the length of the DSRR. The reconfigurability feature is achieved by using two PIN diode switches employed in the two DSRR. The measured results show that the proposed filtering-antenna provides wide impedance bandwidth from 2.58 to 15.5 GHz with controllable dual sharp band notches for WiMAX and HiperLAN, peak realized gain of 4.96 dB and omnidirectional radiation pattern.
