“…Recently, a lot of UWB monopole antennas with single or multiple notch frequencies to avoid this interference have been introduced. The band-notch characteristics can be achieved through various slots or slits in the radiating patch [5][6][7][8][9][10][11], slots in the feed line [12][13][14][15], slots in the ground plane [16][17][18][19], or using parasitic patches [20][21][22][23][24][25][26]. However, these antennas have fixed band-notch characteristics, and in the cases that there is no interference, they are unable to utilize all the UWB frequency range.…”

Abstract-In this paper, a new flower-shaped microstrip line feed reconfigurable band-notched UWB monopole antenna using single varactor diode is introduced and fabricated. Different notch frequencies can be obtained using different capacitance values. The effect of changing the varactor position is also examined. The flower shape is first optimized to obtain UWB characteristics. Then, a slot is made in the microstrip line to be loaded later with a single varactor diode. A wide range of notch frequencies can be obtained using this simple configuration which covers most of the narrow band coexistence systems. The notch frequency can be lower by increasing the capacitance value. The notch frequency covers the WLAN band when C = 0.8 pF and covers the WiMAX band when the capacitance is changed to 0.7 pF for the same antenna configuration and varactor position. Two prototypes of the proposed antenna using two different single capacitor elements with capacitances 0.6 pF and 1.5 pF are fabricated, and their reflection characteristics are measured and compared with the simulated ones. Notch frequencies at 6.1 GHz and 4.3 GHz are obtained respectively in both simulated and measured antenna structures. The proposed antenna has a directive radiation pattern in E-plane and omnidirectional pattern in Hplane. Also, the gain is suppressed in the notched frequencies. The group delay is nearly stable in the UWB frequency range with very little variations, but it is distorted sharply at the notch frequencies. So, the proposed antenna is a good candidate for the modern UWB systems.

“…In the UWB band, there are bands such as radiolocation system (RLS) band (3.1 ̶ 3.7 GHz) as per US National table of frequency allocation, wireless local area network (WLAN) for IEEE 802.11a (5.15 ̶ 5.825 GHz), and X-band satellite communication system (XSCS) band (7.3 ̶ 8.4 GHz) exists which can create interference with UWB system. Hence, UWB antennas with single [6][7][8][9]13], dual [10][11][12][13], and triple [14][15][16][17][18] notched bands are reported.…”

A novel hammer-shaped UWB printed antenna with triple notched stop bands is presented and fabricated on FR-4 substrate with size of 40×40×1.6 mm 3 . The proposed antenna is composed of hammer-shaped patch with Cshaped slot, U-shaped slot on feed line, and inverted stepped notch and bevel edges with pair of L-shaped slots in partial ground plane. The fabricated antenna is tested and obtained impedance bandwidth 2.89 ̶ 11.6 GHz with three notched stop bands 3.15 ̶ 3.7 GHz, 5.45 ̶ 6.8 GHz, and 7.5 ̶ 8.8 GHz, for radiolocation system (RLS), wireless local area networks (WLAN), and X-band satellite communication system (XSCS) bands, respectively. Moreover, the antenna result shows omnidirectional radiation pattern, average gain of 3.10 dBi over the whole UWB band except at the notched frequency bands.

“…Additionally, to prevent the potential interference between the existing operating bands applied to UWB radio systems (3.1 ∼ 10.6 GHz), WiMAX (3.3 ∼ 3.7 GHz) and WLAN (5.15 ∼ 5.35 and 5.725 ∼ 5.825 GHz), band-notched function is appreciable and necessary for a good candidate UWB antenna [1][2][3][4]. Many UWB antennas with band-notched function have been reported in recent years, which mainly use partial ground and feed gap to yield wide working band [5][6][7][8][9][10].…”

Abstract-In this article, a novel microstrip-line fed monopole dual band-notched antenna with tapered slot for UWB applications is presented. The tapered slot, making the antenna have a scissors-like shape, is utilized to enhance the wideband characteristics. In addition, the dual notched bands, from 3.3 to 3.7 GHz and from 5.15 to 5.85 GHz, are achieved by inserting slots on the ground plane and adding circle arc stubs on the radiating patch. Details of the antenna design are described, a theoretical and experimental investigation of the antenna is given as well.
