“…In comparison to [17] the proposed antenna provides better bandwidth performance and in comparison to [4][5][6], it provides strong radiation attenuation at the notch bands. However, in literature various antennas are reported with dual, multiple band notch characteristic [9,13] but their gain performances are low with respect to the proposed antenna. To comprehend the operation of the band rejection mechanism of the slots and radiating element a lumped element equivalent circuit model is developed.…”

“…Various shaped slots have been implemented in the ground plane [7], and radiating patches [8][9][10][11][12], to filter out the unwanted frequency bands. Beside this slot geometry, use of split ring resonator [13], Hilbert curves [14], are another way to notch out the desired frequency band. Stretching the impedance bandwidth beyond the specified UWB range is another challenging task for any RF engineer.…”

Abstract-This paper presents the development of an Ultra Wide Band (UWB) monopole antenna with dual band notch characteristics. Modified crown-square shaped fractal slots in the ground-plane are implemented to enhance the impedance bandwidth to around 58% as compared to conventional square monopole antenna without slots. Impedance bandwidth of the proposed antenna is approximately 114% with Voltage standing wave ratio (VSWR) < 2. In addition to this, two omega-shaped (Ω) slots have been incorporated in the radiating patch to render band-notch characteristics centered at 5.5 GHz band assigned to IEEE802.11a and HIPERLAN/2 as well as X-band for satellite communication centered at 7.5 GHz band. Measured antenna gain is stable over the entire UWB region except at the notch bands. Radiation pattern of the antenna show that the proposed antenna exhibits nearly monopole like E plane radiation patterns and omni-directional H plane radiation patterns throughout the band. A fabricated prototype is developed with close agreement between simulated and measured results.

“…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 .

“…The band notch characteristics can be obtained through different slots in radiated patch [6], fed line [7], slots in ground [8], and also parasitic patch [9]. Also a notch can be obtained using a quasi-complementary split ring resonator (CSRR) in fed line [10][11][12][13][14][15][16] or EBG structure etching on patch/ground plane [17].…”

In this paper, CPW-Fed ultra wideband (UWB) planar monopole antenna (PMA) loaded by double elliptical split ring resonators (ESRRs) for double band-notch characteristics is introduced and examined. Two different ESRRs with different dimensions are printed in the antenna backside to notch two different frequencies. The ESRRs are also rotated and the corresponding return loss effect is examined. Different notch frequencies can be obtained by varying the ESRRs, dimensions. Two single SRRs are used to notch two frequencies instead of using dual SRR pairs. Two notch frequencies at 5.2 GHz and 6.9 GHz has been obtained to notch WLAN and C-band wireless applications, respectively. A directive radiation pattern in E-plane and omnidirectional radiation patterns in the H-plane could be observed. Also the gain is suppressed in the notch frequencies. The group delay is nearly stable in the UWB frequency range, except at the notch frequencies, which is distorted sharply. So, the proposed antenna is a good candidate for the modern UWB systems. Finite element method FEM and finite integration technique FIT are used to simulate the proposed structures through the usage of Ansys HFSS and CST MWS. Very good agreement between both results has been obtained.
