“…Furthermore, the result also reveals that the final design unit cell-C operates at six stopband frequencies (0.4, 0.67, 0.69, 0.95, 1, and1.14 THz) with return loss of 15, 35, 17, 56, 46, and 17 dB, respectively. The effective parameters of the metamaterial such as refractive index (n), permeability (μ), permittivity (ε) and impedance (Z) should be verified through the S-parameters of the unit cell given by the equations from ( 1)-( 5) and can extract by the MATLAB software or by the built-in CST postprocessing [29][30][31].…”

“…In the past few decades, the idea of metamaterials has attracted great attention and achieved great successes in the area of engineering and science. Metamaterials are artificially engineered materials with properties not easily found in natural materials such as negative permeability, negative refractive index, and negative permittivity [29][30][31]. These properties allowed researchers and scientists to explore the use of metamaterials in numerous applications at the terahertz regime.…”

A multi-band metamaterial antenna is proposed to operate at the terahertz (THz) band for medical applications. The proposed structure is designed on a polyimide as a support layer, and its radiating elements are made of graphene. Initially, the design is started with a conventional shape showing a single operating frequency at 1.1 THz. To achieve a multi-band operating frequency, the conventional shape was replaced with the proposed metamaterial as a radiating patch that has properties not exist in nature. The multi-band frequencies are obtained without compromising the overall size of the design. The overall size is 600 × 600 × 25 μm 3 . The operating frequencies are 0.36, 0.49, 0.69, 0.87, and 1.04 THz. A full ground plane is used to behave as isolation between the design and the human body model. The proposed design is investigated on free space and on the human body model, showing excellent performance in both cases. The achieved gains for the following frequencies 0.36, 0.49, 0.69, 0.87, and 1.04 THz are 4.81, 6.5, 8.41, 6.02,and 7.96 dB, respectively, while the efficiencies are 83.91%, 96.28%, 90.80%, 91.71%, and 92.99%, respectively. The conventional design was modified to have a partial ground to show the benefit of using the full ground. The design is loaded on the human body model and its performance is affected. The efficiency and gain are 6.61 dB and 95.58.7% for the case of no human body model, and 4.26 dB and 40.30% for the case of using a human body model. Hence, the proposed metamaterial antenna will be useful for future medical applications in the THz band.

“…The CPW fed planar antennas [6][7][8], a spiral CSRR loaded antenna [9], and a circular SRR inspired antenna [10] are proposed for single-band operation. A hexagonal split-ring metamaterial-inspired dualband antenna [11], a circular CSRR inspired cross-shaped dual-band antenna [12], and a triangular SRR metamaterial-inspired dual-band antenna [13] are designed for WLAN applications. An SRR inspired antenna [14], an electric LC loading based on Koch shaped fractal metamaterial antenna [15], a metamaterial slot inspired substrate waveguide antenna [16], a complementary capacitive-loaded loop antenna [17], a metamaterial with ELC and EBG loading antenna [18], a metamaterial inspired mushroom loaded antenna [19], a dumbbell shaped metamaterial inspired antenna [20], and a modified complementary hexagonal spiral resonator inspired antenna [21] have been realized for multiband performances, which are not focused on specific applications.…”

In this article, a novel Hexagonal Split-Ring Resonator enclosed Circular Split-Ring Resonator (HSRR-CSRR) inspired printed antenna is presented for sub-6 GHz 5G NR and IEEE 802.11ba/be applications. The proposed antenna comprises an HSRR-CSRR and a D-SHSRR metamaterial unit cell with a partial ground plane. The designed antenna is printed on a low-cost FR-4 substrate with dielectric constant ε r of 4.4, thickness of 1.6 mm, and loss tangent of 0.02. An HSRR-CSRR metamaterial structure is designed to get the three distinct resonance frequencies at 3.5 GHz, 5.05 GHz, and 6.2 GHz, respectively. To cover the entire band of Sub-6 GHz 5G NR (5-6 GHz), a Double-slit Single Hexagonal Split Ring Resonator (D-SHSRR) is designed for 5.8 GHz and loaded along with the HSRR-CSRR. The operating principle, equivalent circuit, and parametric extraction of the HSRR-CSRR structure are examined. Compared to the conventional antenna, the proposed antenna has a compact size of 0.38λ g × 0.52λ g × 0.03λ g . The antenna parameters have been investigated using Ansys HFSS 15.0 software. The measured and simulated results are in good agreement.

“…The use of multiple antennas within modern devices is not ideal owing to their tiny size. So, the ideal solution is to use a multi-band antenna to reduce the number of the needed antennas inside the compact systems [1][2][3]. Another issue related to the need for multi-band antennas is the increasing number of wireless applications.…”

This article presents a highly miniaturized dual-band electrically small antenna (ESA) for on-demand 3.6 and 5.8 GHz wireless applications. A partial rectangle-shaped structure is printed on the back face of the dielectric material, forming the antenna's ground (GND) plane. The radiating structure of the antenna consists of a C-shaped structure and a U-shaped ring connected to it, which is printed on the dielectric material's front face. The overall dimensions of the designed antenna are 0.160λo × 0.160λo × 0.02λo at the lowest operating frequency. The proposed antenna has a ka value of 0.56 at the lowest operating frequency, which is 3.59 GHz. Thus, the proposed antenna is considered as electrically small. The characteristic mode analysis is adopted to provide a clear understanding of the antenna's resonance behavior. The antenna has been fabricated and the simulation results were validated through measurements. Good agreement between simulated and measured results was obtained. Dual-band operation at 3.62 and 5.75 GHz was achieved, according to the measured reflection coefficient. The proposed antenna offers an adequate performance in terms of gain and efficiency, based on simulation and measurement results. Because of these characteristics, the antenna is well-suited to new wireless applications.
