A Bandwidth and Gain Enhanced Hexagonal Patch Antenna using Hexagonal Shape SRR

In the evolving digital era, the primary focus of the telecommunications industry is on the 5G network, expected to deliver high data rates, low latency, large network capacity, and improved connectivity. This article discusses efforts to adopt optimal frequencies for 5G, introducing techniques to enhance the characteristics of microstrip antennas using Double Negative (DNG) metamaterial properties. The hexagonal-shaped Split Ring Resonant (HSRR) metamaterial is considered a potential method to increase the bandwidth and gain of 5G antennas. Simulation of HSRR unit cells shows a positive impact on DNG characteristics. Meanwhile, the antenna design incorporating HSRR superstrate elements significantly increases gain to 4.47 dBi, and the implementation of HSRR structures on the groundplane results in a remarkable 368% increase in bandwidth compared to conventional antennas without metamaterial.

Design and mathematical modeling of DNG metamaterial having six-band capabilities with high effective medium ratio

ABSTRACT In this paper, six-band double negative (DNG) metamaterial with a substantially high effective medium ratio (EMR) under the S and C microwave band is designed and investigated for multiple microwave applications. The proposed metamaterial unit cell consists of four Plus Appended Split Ring Resonator (PASRR) cells, which are combined with variable sides and positions by plus (+) shape stubs at the centre. All four Plus Appended Split Ring Resonator (PASRR) cells are mutually coupled with each other to vary the electrical length to achieve hexa Bands DNG characteristics in a lossy FR-4 epoxy substrate with the thickness of 1.5748 mm. A parameter extraction method has been used to extract effective permittivity (ε eff), permeability (μ eff) and refractive index (n). Moreover, the equivalent circuit model is obtained. Ansys HFSSTM software & Keysight ADSTM software are used to obtain the simulated and theoretical results, respectively, which agree measured with simulated and theoretical results.

Ultra-wideband Metamaterial-based Rectangular Microstrip Antenna for Sub-6 GHz 5G and other Microwave Applications

This paper presents a novel design of an ultra-wideband metamaterial-based rectangular microstrip antenna for sub-6 GHz 5G and other microwave applications. The proposed antenna consist of a rectangular microstrip patch, two metamaterial unit cells, Flame Resistant (FR-4) substrate and partial ground plane. The metamaterial unit cell comprises complementary split ring resonator (CSRR) with double negative characteristics (negative permeability and negative permittivity) as well as negative refractive index (NRI). The NRI medium enhanced the bandwidth and radiation efficiency of the antenna by reducing the surface waves and mutual coupling. The antenna operates over frequency range of 3.4009 to 11.721 GHz and 2.869 to 3.211 GHz, covering the sub-6 GHz 5G bands and other microwave applications such as Wi-Fi, WiMAX, and WLAN. Also, the proposed antenna had optimized dimensions of and exhibited good impedance matching, omnidirectional radiation pattern, and stable gain across the operating band. From simulation results, a combined bandwidth of 8.66 GHz was achieved which shows good agreement with outlined objective. The proposed antenna is suitable for sub-6 GHz 5G and other microwave applications that require ultra-wideband performance and low-profile design.

Multiple Re‐Entrant Star‐Shaped Honeycomb with Double Negative Parameters and Bandgap Properties

Achieving bandgaps and double negative properties with single‐phase metamaterial in the low‐frequency range remains a challenge. Currently, acoustic metamaterials with double negative parameters are made of different materials, which can limit their application and design. Herein, a single‐phase multiple re‐entrant star‐shaped honeycomb (MRSSH) is designed and the double negative parameters and bandgaps are simulated. The numerical results show that the MRSSH exhibits three bandgaps and double negative characteristics (negative effective mass density and negative effective modulus) within a certain frequency range. The formation mechanics of bandgaps are investigated by analyzing the vibration modes. Moreover, the effects of geometry parameters such as internal concave angle and re‐entrant on the bandgaps and vibration modes of the MRSSH are investigated. By adjusting the geometry parameters, the dispersion curves and bandgap distribution can be tuned simultaneously. This study provides a new idea for designing a single‐phase lightweight metamaterial that can apply to noised reduction, vibration control, and super‐resolution imaging.

Analysis and design of double negative metamaterial offering seven operating bands with minimum frequency ratio

ABSTRACT A novel plus (+) shaped metamaterial’s (MTM) unit cell is introduced and investigated, which exhibits double negative (DNG) characteristics at seven different frequency bands of a minimal frequency ratio of 1.0953:1. DNG characteristics at seven bands are achieved in a dielectric substrate of dielectric constant 4.4. The permittivity (ε), permeability (μ) and refractive index n of the proposed MTM are extracted. Furthermore, circuit modeling of the introduced MTM is executed through transmission line theory and an equivalent circuit model (ECM) is realized for its theoretical analysis. The developed ECM is put through Keysight ADS™ software to verify the theoretical results. Dispersion equations of the invented MTM are also established, which figure out the zeroth-order frequency at its dominant mode. Simulation analysis is accomplished through Ansys HFSS™ software and both the theoretical and simulated results are verified by measured results of fabricated prototype.

Metamaterial based on an inverse double V loaded complementary square split ring resonator for radar and Wi-Fi applications

In this research paper, an inverse double V loaded complementary square split ring resonator based double negative (DNG) metamaterial has been developed and examined numerically and experimentally. The electromagnetic (EM) properties of the proposed inverse double V-structure were calculated using computer simulation technology (CST-2019) and the finite integration technique (FIT). The designed metamaterial provides three resonance frequencies are 2.86, 5, and 8.30 GHz, covering S-, C-, and X-bands. The total size of the recommended unit cell is 8 times 8 times 1.524 mm3, and a high effective medium ratio (EMR) value of 13.11 was found from it. The − 10 dB bandwidths of this structure are 2.80 to 2.91, 4.76 to 5.17, and 8.05 to 8.42 GHz. The proposed structure's novelty is its small size, simple resonator structure, which provides double negative characteristics, high EMR, maximum coverage band, and required resonance frequencies. Wi-Fi network speeds are generally faster when frequencies in the 5 GHz band are used. Since the proposed structure provides a 5 GHz frequency band, hence the suggested metamaterial can be used in Wi-Fi for high bandwidth and high-speed applications. The marine radars operate in X-band, and weather radar works in S-band. Since the designed cell provides two more resonance frequencies, i.e., 2.86 GHz (S-band) and 8.30 GHz (X-band), the proposed metamaterial could be used in weather radar and marine radar. The design process and various parametric studies have been analyzed in this article. The equivalent circuit is authenticated using the advanced design system (ADS) software compared with CST simulated result. The surface current, E-field, and H-field distributions have also been analyzed. Different types of array structure, i.e., 1 times 2, 2 times 2, 3 times 3, 4 times 4, and 20 times 25 is examined and validated by the measured result. The simulated and measured outcome is an excellent agreement for the inverse double V loaded CSSRR unit cell and array. We showed the overall performance of the suggested structure is better than the other structures mentioned in the paper. Since the recommended metamaterial unit cell size is small, provides desired resonance frequency, gives a large frequency band and high EMR value; hence the suggested metamaterial can be highly applicable for Radar and Wi-Fi.

Polarization-independent multiband double-negative metamaterial through ferrite-based flexible substrate with tunable microwave dielectric properties

Microwave flexible dielectric materials offer a new set of attractive applications for modern devices as well as for metamaterial research and technology. In this article, metamaterials with double-negative characteristics fabricated on a novel flexible dielectric substrate are presented. These novel flexible microwave substrates were prepared from Mg-Zn ferrite powder. The proposed flexible metamaterials offer double-negative (DNG) properties, polarization insensitivity, and a higher effective medium ratio (EMR) for multiple bands of application. The prepared, flexible substrates exhibit performance superior to commercial materials with tunable dielectric properties, and the proposed metamaterial structure enhances the antenna performances as well. The flexible substrates are synthesized from Mg-Zn ferrite having two different molecular compositions of Mg denoted as Mg40 and Mg60. The prepared, highly flexible, and lightweight magnesium zinc ferrites of Mg40 and Mg60 possess tunable dielectric properties with relative dielectric permittivity of 5.18 and 4.20 and dielectric loss tangents of 0.004 and 0.006, respectively. The double-negative (DNG) metamaterial behavior is observed with the fabricated flexible metamaterials at 2.92 GHz, 4.42 GHz, 7.75 GHz, and 9.84 GHz for Mg40 and 3.16 GHz, 4.71 GHz, 8.21 GHz, and 10.52 GHz for Mg60 and validated by using 3D electromagnetic Simulator CST (Computer Simulation Technology) Microwave Studio and ADS (Advanced Design System) software. Therefore, the prepared, flexible metamaterials having improved EMR, polarization insensitivity, and DNG properties on a MgZnFe2O4substrate are suitable additions to the field of the flexible microwave.

Broadband gain enhancement of an UWB antenna using conformal wideband NRI metamaterial

Abstract In this article, broadband gain enhancement of an ultra-wide band (UWB) antenna is achieved by using 4 × 4 array of a wideband negative refractive index (NRI) metamaterial as a reflector layer. A novel shaped metamaterial sized 14.8 × 14.8 mm2 with double negative (DNG) characteristics in three frequency regions has been fabricated on a flexible FR4 with 0.25 mm thickness. The proposed metamaterial gives a continuous NRI bandwidth of 10 GHz (2–12 GHz). The effective parameters of the unit cell cover S, C, X, and Ku-band independently and show DNG region of 6.1 GHz at C (4–8 GHz) and X band (8.8–10.5 GHz, 11.2–11.6 GHz). The unit cell structure is also found to be feed insensitive. The unit cell has small volume of 54.76 mm3 along with flexible nature which makes it suitable for wearable applications. For a 4 × 4 array the metamaterial still exhibits DNG characteristics. To understand the physical behavior of the unit cell, the circuit analysis along with the study of magnetic and electric field distribution at three resonance frequencies (2.2, 8.2 and 14.2 GHz) is done. Both simulation and measured results indicate that the gain and bandwidth of metamaterial antenna are enhanced by 2 dB and 0.8 GHz.

Metamaterial based circularly polarized four-port MIMO diversity antenna embedded with slow-wave structure for miniaturization and suppression of mutual coupling

An engineered metamaterial is proposed for achieving the circular polarization and suppression of mutual coupling in closely placed four-port MIMO (multi-input multi-output) antenna. Data rate and channel capacity (bits/s/Hz) are enhanced four times as all the four ports of the proposed MIMO antenna are radiating and receiving the signals within the same frequency band. Secondly, the recommended antenna doesn’t radiate harmful electromagnetic radiations as it carries low profile characteristics. Design equations are also developed through which antenna could be designed at any desired frequency of interest. Before the analysis of antenna, the unit cell of the metamaterial is analyzed and its double negative characteristics are verified at the resonant frequency. Further, a slow-wave structure is designed and investigated with a microstrip line; subsequently, it is embedded with the proposed antenna structure to refine the characteristics of the antenna. Highly suppressed mutual coupling of the value of −40 dB is achieved between diagonal-ports of the antenna. The proposed antenna offers uncorrelated radiations with satisfactory gain, axial ratio and minimum mutual coupling. The prototype of the proposed structure is manufactured to validate the simulated results with experimental results.

To deal with this contention, a microstrip framework consisting of a dual mode double negative (DNG) metamaterial based bandpass filter is presented in this article.

Preparation and properties of a left-handed metamaterial composite

ABSTRACTA left-handed metamaterial (a YIG/Ag composite with adjustable negative permittivity and permeability) was prepared by an in situ synthesis process, and its characterisation, microstructure, electrical conductivity, dielectric loss and magnetic properties studied. A negative permittivity behaviour with a Fano-like resonance is ascribed to plasma oscillation of delocalised electrons from silver conducting networks. As the silver content increases, the turbine loss increases, which greatly enhances the electromagnetic wave consumption capacity inside the material and leads to a stronger electromagnetic absorption and shielding performance. The dielectric loss near the percolation threshold is due to the combined effects of polarisation and conduction. The capacitive character is responsible for positive permittivity, and the inductive character leads to negative permittivity. LC resonance results in the Fano-like resonance, leading to the permittivity changing from negative to positive. Gyromagnetic spin rotation, domain wall motion and percolation characteristic of YIG/Ag composites cause frequency dispersion of the permeability. The YIG/Ag composite with double negative characteristics provides prospects for electromagnetic shielding application.

Abstract In this article, a modified Theta shaped, compact double negative metamaterial structure is designed and presented for satellite communication. Two oppositely faced E-shaped resonators are connected with the substantial Theta to complete the structure. A low profile dielectric substrate FR-4 is used to design the 9 × 9 mm2 unit cell which has a succinct structure where the attainment of the resonator is explored both integrally and experimentally. The proposed metamaterial has a transmission coefficient of 13 GHz (bandwidth) with a 500 MHz band gap at the middle. A correlation is made between the basic unit-cell and array structures, and a comparison is shown among 1 × 2, 2 × 2, and 4 × 4 array structures with 1 × 2, 2 × 2, and 4 × 4 unit-cell configurations to validate the performance of the proposed metamaterial. It has also been observed by the Nicolson–Ross–Weir approach at the resonating frequencies. The effective electromagnetic parameters retrieved from the simulation of the S-parameters imply that the metamaterial structure shows negative refraction bands. The structure shows negative permittivity at 2.60 to 5.16 GHz, 6.63 to 9.31 GHz and 13.03 to 16.18 GHz and negative permeability at 7.74 to 13.07 GHz and 13.88 to 16.55 GHz, respectively. It exhibits double-negative phenomena at X and Ku bands with a frequency range of about 1.17 GHz (8.14 – 9.31 GHz) and 1.42 GHz (13.80 – 15.22 GHz), respectively. Having an auspicious design and wide range double negative characteristics, this structure can be applied to satellite communication.

A Compact Ultrawideband Antenna Based on Hexagonal Split-Ring Resonator for pH Sensor Application.

A compact ultrawideband (UWB) antenna based on a hexagonal split-ring resonator (HSRR) is presented in this paper for sensing the pH factor. The modified HSRR is a new concept regarding the conventional square split-ring resonator (SSRR). Two HSRRs are interconnected with a strip line and a split in one HSRR is introduced to increase the electrical length and coupling effect. The presented UWB antenna consists of three unit cells on top of the radiating patch element. This combination of UWB antenna and HSRR gives double-negative characteristics which increase the sensitivity of the UWB antenna for the pH sensor. The proposed ultrawideband antenna metamaterial sensor was designed and fabricated on FR-4 substrate. The electrical length of the proposed metamaterial antenna sensor is 0.238 × 0.194 × 0.016 λ, where λ is the lowest frequency of 3 GHz. The fractional bandwidth and bandwidth dimension ratio were achieved with the metamaterial-inspired antenna as 146.91% and 3183.05, respectively. The operating frequency of this antenna sensor covers the bandwidth of 17 GHz, starting from 3 to 20 GHz with a realized gain of 3.88 dB. The proposed HSRR-based ultrawideband antenna sensor is found to reach high gain and bandwidth while maintaining the smallest electrical size, a highly desired property for pH-sensing applications.

Exceptional electromagnetic interference shielding and microwave absorption properties of room temperature synthesized polythiophene thin films with double negative characteristics (DNG) in the Ku-band region

Negative refractive index (NRI) metamaterials with simultaneously negative permittivity and negative permeability have recently experienced tremendous fundamental and practical interest due to their unique electromagnetic properties. In this work, polythiophene (PTh) thin films were synthesized using an in situ chemical oxidative polymerization route. The double negative characteristics (negative permittivity and permeability) appeared simultaneously in the as-prepared PTh thin films. The structural and microstructural characterizations of as-deposited PTh thin films were examined through different techniques including XRD, FESEM, TEM, XPS and FT-IR spectroscopy. Furthermore, microwave absorption properties such as reflection loss (RL), shielding effectiveness (SE) of the PTh thin films with varying monomer concentration were also investigated. The morphological investigation shows that the unique porous microstructure of the PTh fibers has a dramatic impact in the enhancement kinetics of the microwave absorption performance. The PTh fibers deposited at 0.2 M concentration of thiophene showed minimum reflection loss (RL) of −44.24 dB (99.9% microwave absorption) at 17.59 GHz frequency, with a total shielding effectiveness of −18 dB at 16.3 GHz with only 5.31 microns of matching thickness. The PTh thin films exhibit exceptional microwave absorption ability at a fairly thin thickness and show a greater effective absorption bandwidth (RL < −10 dB) in the Ku-band region; these findings definitely pave the way to explore the study of different conducting polymer materials for utilization in EMI-shielding applications.

Double-split labyrinth resonator with defective ground system for wide-band band-stop filter application

A labyrinth resonator with defective ground structure (DGS) is introduced for designing a wide-band band-stop filter in order to adjust the resonating characteristics by varying the dimension of the structure to cover 2.75 – 10.30 GHz. A series of modified double-split ring resonators (DSRRs) are embedded into a 50Ω microstrip framework to attain a labyrinth structure. The Rogers RO- 3010, which has a succinct structure, is used as the substrate in the proposed wide-band band-stop filter. The realization of the architecture is explored both integrally and experimentally, and a complementary split ring resonator (CSRR) is introduced in the ground layer. The level of rejection of the filter in the stop-band region increases with the introduction of the CSRR. In addition, the filter is evaluated by applying the Nicolson-Ross-Weir approach at the filtering frequency. The effective electromagnetic parameters retrieved from the simulation of the S-parameters imply that the metamaterial structure exhibits negative refraction bands. With a promising design and wide range of double-negative characteristics, we propose a new type of filter which is suitable for a wide-band band-stop application.
