“…Due to the influence of mutual coupling, when the J-shaped slit is embedded in the ground plate, the suppression band of the CSRR is shifted [25][26][27][28]. When the spiral slit is embedded in the radiation patch, the suppression band of the CSRR is shifted, but at this time, the suppression band of the J-shaped slit is not significantly affected.…”

A novel ultra-wideband (UWB) printed monopole antenna with triple band-notched characteristics is proposed in this paper. The antenna bandwidth is extended by grooving on the connecting floor and increasing the impedance transformation line, with antenna bandwidth of 3.0∼11 GHz and relative bandwidth of 114%. The overall antenna size is 35 × 30 mm 2 . The complementary split-ring resonators (CSRRs) are loaded on the UWB antenna patch with microstrip wire feed. A symmetric J gap is loaded on the bottom plate, and the spiral gap is loaded on the feeder. The triple band-notched characteristics at 3.22∼3.97 GHz, 4.94∼5.84 GHz, and 7.25∼7.86 GHz bands are realized. The gain of the designed antenna in the notch frequency segment can be reduced rapidly to −4 dbi, while the gain of other frequency bands is above 2 dBi. Simulated and measured results show that the antenna has stable gain and good radiation characteristics in the UWB frequency range.

“…This can also be done by adding strips or stubs adjacent to the radiator or ground or feed line as discussed in [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. Each slot or strip can function as a resonator, and the slot or strip length controls the notch center frequency.…”

“…The proposed antennas in [11][12][13][14][15][16][17] mostly reject WLAN band only. Dual band-notched functions for UWB-MIMO antennas can be realized by employing nested C-shaped slots in the patch [18], etching 1λ loop path and 0.25λ slot on radiator [19], introducing strips beneath the patch [20], placing open-ended slot and SRR in the ground [21], placing a parasitic strip and open-ended slot on ground [22], or by loading trident-shape strip on the patch [23].…”

“…A number of experiments were done earlier to integrate the single and multiple band-notch functions for UWB systems and hence to mitigate the frequency interference from narrowband systems [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. Methods such as etching λ/4 and λ/2 resonators on the ground [11], introducing split-ring resonator (SRR) slots on radiator [12], incorporating two rectangular strips on the ground plane [13], etching a 1λ slot into radiator [14], slitting λ/4 open-ended L-shaped slots on the radiator elements [15], employing λ/4 and λ/2 resonators [16], and using elliptical SRR on the radiator [17].…”

Abstract-A very compact triple band-notched multiple input multiple output antenna (MIMO) for ultra-wideband (UWB) communications is fabricated on an FR4 dielectric substrate having the overall size of 18 × 21 × 0.8 mm 3 . The proposed antenna consists of two rectangular metal monopoles which are excited by 50-Ω microstrip lines on top of a substrate, and a common protrude ground is at the bottom. To achieve low mutual coupling between radiating elements, a T-shaped stub is protruded from the ground plane. By etching two C-shaped slots on the radiating patches, band-notched functions at 5.15-6 GHz and 7.8-8.4 GHz are obtained. The third notch band from 3.3-3.7 GHz is realized by adding Ushaped metal strips to the ground. The measured and simulated results demonstrate that the proposed antenna offers good impedance bandwidth of |S 11 | ≤ −10 dB from 2.8-12.2 GHz covering whole UWB band except at the designed notch bands, while giving less mutual coupling (|S 21 |) of lower than −25 dB in the whole UWB band. The measured envelope correlation coefficient (ECC < 0.013), nearly constant gain and stable radiation patterns show that the proposed MIMO antenna is an appropriate candidate for portable UWB systems.

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 .
