“…A conventional slot with open-ends and a quarter-wavelength is engraved in the radiator, and three half-wavelength semi-circular slots are cut in the radiator to produce the triple band rejection antenna in [8]. Expending analogous ideas for triple notched antennas are suggested by different authors in [9][10][11][12]. In [13] a triple band rejection notched antenna using electric ring resonator is shown.…”

Abstract-A MIMO/Diversity antenna with triple notch characteristics is proposed in this article. The proposed antenna has triple notches in the WiMAX band (3.3-3.6 GHz), WLAN band (5-6 GHz), and X-band satellite communication (7.2-8.4 GHz) band. Defected Ground Compact Electromagnetic Band Gap (DG-CEBG) is a design used to accomplish band notches. Defected ground planes are utilised so as to achieve compactness in conventional EBG structures. The proposed WiMAX band, WLAN band, and X-band satellite communication band DG-CEBG structures show a compactness of around 46%, 50%, and 48%, respectively, over a conventional EBG structure. In these structures, decoupling strips and a slotted ground plane are used to enhance the isolation between two closely spaced UWB monopoles. The individual monopoles are 90 • angularly separated with a stepped structure which helps to reduce mutual coupling and also contributes towards impedance matching by increasing the current path length. |S 21 | or mutual coupling is found to be less than 15 dB over the whole UWB frequency range. The Envelope Correlation Coefficient (≤ 0.5) is within the acceptable limits over the whole UWB frequency range. Notched frequency depends on the parameters of DG-CEBG structures; when there is a change in these parameters notch frequency is also changed. A low cost FR-4 substrate with thickness (h) = 1.6 mm, permittivity (ε) = 4.4 and loss tangent (δ) = 0.02 is used for the proposed antenna, and it has a compact size of 58 × 45 × 1.6 mm 3 .

“…A feasible way is to implement band notching in UWB antenna to mitigate the interference. However designing and placement of these notch creating structures are challenging as compared to the traditional RF filtering technique [6,7]. In spite of the fact that different UWB printed antennas with band-notched functionality have been as of late displayed, a large portion of which were composed with one notched band [8], two notched bands [9], or three notched bands [10] at their mentioned frequency bands.…”

Abstract-A sharply rejected dual notch band UWB monopole antenna is presented in this paper. The proposed antenna consists of maple leaf shaped radiating element, a 50 Ω microstrip feed line and truncated ground plane. The proposed antenna shows the UWB operation in the frequency range (1.7 GHz-11.1 GHz) with VSWR < 2 except the notch bands and two band notches centered at 4.3 GHz and 7.7 GHz. The band notches are achieved by introducing a meandered slot in the radiating element and U-shaped slot in feed line. The substrate used for designing of UWB antenna is low loss Rogers 5880 having relative permittivity of 2.2. The novelty of the proposed antenna is its shape and ability to support UWB bandwidth requirements, and it also rejects two bands to avoid possible interference with existing communication system. Good agreement between the simulated and measured results is observed. The proposed antenna has good gain and efficiency at pass bands.

“…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.
