“…The radiation beam pattern in H-plane is omnidirectional because the energy is radiated in all directions (180) without NZIM and it's become directional with the NZIM metamaterial (about 75). As a summary, the mentioned design can be considered as a one of good candidate to challenge the antenna conceptions in the recent technology [10], [11], [12]. Fig.…”

A Near Zero refractive Index (NZIM) metamaterial inspired UWB circular antenna as a superstrate for gain and directivity improvement’s is presented and investigated in this work. The frequency range with S11 less than -10dB is from 4.5GHz to 12.5GHz. The permeability and permittivity of the (NZIM) has an extraordinary property that could be optimized to synchronously approach zero and have an effective wave impedance matching with air and near-zero index simultaneously, this feature of metamaterial gives the NZIM the ability to collimates the incident bending waves and gather it’s towards the normal direction. Hence the antenna performances in term of the gain and directivity will be enhanced. The studied metamaterial design is optimized and analyzed using CST microwave. Obviously, the antenna gain and directivity are enhanced by 4.8 and 4.89 respectively. The simulation of this developed metamaterial antenna has been optimized and performed by using Computer Simulation TechnologyMicrowave Studio (CST) and Ansof High Frequency Structure Simulator (HFSS)

“…To embed the benefits of SWB technology in practical wireless applications, multidimensional research has been undertaken for diverse antenna configurations. For the purpose of achieving wider bandwidth, many different kinds of bandwidth enhancement techniques, such as modification in the ground plane and the patch [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ] along with a diverse range of feeding techniques, such as microstrip tapered feedline [ 9 , 10 , 11 , 12 , 13 ] and Coplanar Waveguide (CPW) feed [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ], have been proposed by antenna designers. To miniaturize the dimension of antenna without impacting the impedance bandwidth, self-similarity structures, such as fractal geometry [ 22 , 23 , 24 , 25 , 26 , 27 ], have been envisioned in the literature.…”

“…Elliptical-shaped patch, fed with tapered microstrip feedline, is designed to exhibit extremely broad bandwidth from 640 MHz to 16 GHz. Although a higher peak gain is stated, the structure of the antenna is large 150 mm × 150 mm to be incorporated into portable devices [ 9 ]. A Hanning function-based tapered microstrip monopole antenna is presented to provide a wide frequency range from 2.5 to 110 GHz [ 10 ].…”

In this article, a compact concentric structured monopole patch antenna for super wideband (SWB) application is proposed and investigated. The essential characteristics of the designed antenna are: (i) to attain super-wide bandwidth characteristics, the proposed antenna is emerged from a traditional circular monopole antenna and has obtained an impedance bandwidth of 38.9:1 (ii) another important characteristic of the presented antenna is its larger bandwidth dimension ratio (BDR) value of 6596 that is accomplished by augmenting the electrical length of the patch. The electrical dimension of the proposed antenna is 0.18λ×0.16λ (λ corresponds to the lower end operating frequency). The designed antenna achieves a frequency range from 1.22 to 47.5 GHz with a fractional bandwidth of 190% and exhibiting S11 < −10 dB in simulation. For validating the simulated outcomes, the antenna model is fabricated and measured. Good conformity is established between measured and simulated results. Measured frequency ranges from 1.25 to 40 GHz with a fractional bandwidth of 188%, BDR of 6523 and S11 < −10 dB. Even though the presented antenna operates properly over the frequency range from 1.22 to 47.5 GHz, the results of the experiment are measured till 40 GHz because of the high-frequency constraint of the existing Vector Network Analyzer (VNA). The designed SWB antenna has the benefit of good gain, concise dimension, and wide bandwidth above the formerly reported antenna structures. Simulated gain varies from 0.5 to 10.3 dBi and measured gain varies from 0.2 to 9.7 dBi. Frequency domain, as well as time-domain characterization, has been realized to guide the relevance of the proposed antenna in SWB wireless applications. Furthermore, an equivalent circuit model of the proposed antenna is developed, and the response of the circuit is obtained. The presented antenna can be employed in L, S, C, X, Ka, K, Ku, and Q band wireless communication systems.

“…Another method is to design the SWB antenna with band notch characteristics without affecting the size and complexity. In literature, different types of SWB antennas, including fractal, printed monopole has been proposed [2]- [6]. However, none of them neither covering important frequency bands like GSM-900, 1800, Wi-Fi 2.1 and 2.4 GHz nor offering band rejection property.…”

This paper presents a patch loaded slot antenna for super wideband (SWB) application. To obtain SWB characteristic, the proposed antenna geometry combined a rectangular slot and an overlying patch excited by a trident shaped microstrip feed. It is observed that the hybrid nature of the proposed antenna effectively enhances the impedance bandwidth up to 120%, by combining the resonance of both patch and slot. Besides, it is investigated that after converting the conventional tapered feed into the trident shape feed, the impedance bandwidth is increased further from 120% to 167% ranging between 1.25 to 15 GHz. Moreover, one U-shaped slot and two L-shaped stubs are inserted into the antenna design to introduce the dual-band rejection property from 1.8 to 2.4 GHz (GSM 1800, Wi-Fi 2.1 and 2.4) and 3.1 to 4.2 GHz (WiMAX and C-band). Further, to validate the simulation results a prototype is fabricated and tested. The measured result shows that the proposed antenna offered an impedance bandwidth of 170.3% from 1.2 GHz to 15 GHz.
