“…Split-ring resonators (SRR) have been employed for multi-band antennas for multiple applications. In essence, simple printed monopoles or dipoles have been loaded with slots to produce resonance frequencies [ 29 , 30 , 31 , 32 , 33 ]. In most cases, the slots are inserted at strategic points where the current flow is less predominant.…”

In this study, we present a low-profile dual-spectrum split-ring monopole that operates at industrial, scientific and medical (ISM) (2.45 GHz) band and ultrawideband (UWB) spectrum (3.1–10.6 GHz). We optimised the design for dual-band operations by using circular split-ring radiators. The coupling between both rings drives the structure to achieve quasi-resonance frequencies in the UWB spectrum. A small stub combines the two radiators and both behave as a single element that enables the antenna to resonate at ISM band 2.45 GHz. The antenna achieves the desired characteristics in terms of good impedance matching, radiation properties as well as other physical and practical requirements such as compact geometry, planar profile and easy fabrication. The very good agreement between the simulated and measured results show that the proposed antenna has the potential for dual-band application.

“…With the outward oscillating field the induced dipole moment in the satellite radiography may be calibrated for a positive or negative magnetic permeability either in or out step. Thus, even though the metal used to create the SRR is non magnet, an artificial magnetism can be obtained [20][21][22]. Analysing such small size electromagnetic devices and sensors in two dimensions is not preferred.…”

The study presents 3D electromagnetic analysis and optimization of metamaterial constructed split ring resonator. The analysis was carried out under electromagnetic analysis conditions by using electromagnetic boundary conditions master and slave. The operating frequency range, in other words the performance characteristic, has been analysed from 1 GHz to 20 GHz. The split-ring resonator design has been analysed on triple co-axes in accordance with its actual use. Surface current density, electric field strength and magnetic field strength values were examined in the analysis. Metamaterial based split-ring resonators are used in many fields. Today, it has many applications as measurement and sensor or as antenna in 5G applications. In order to obtain a suitable design at high frequencies, micron-level designs are required. Newly developed objective functions are presented in the study. In this study, good results were obtained with an optimized SRR design by using multi-objective genetic algorithm in the range up to 20 GHz that can achieve negative refractive index capacity. These results are presented in the study with the relationship between permittivity and permeability. Furthermore, when the results obtained from the design are examined, it is seen that it is suitable for wireless applications. Performance improvement have been carried out SRR negative refractive index capacity which before has 11 GHz was increased to 15.5 GHz.

“…Using the normal incidences data of scattering parameters, a robust approach is used to obtain the valuable metamaterial parameters 46 . The transmission (S21) and reflection coefficients (S11) of the designed MTM unit cell are first evaluated using simulations in the frequency span from 2 to 4 GHz.…”

An integrated massive multiple-input multiple-output (mMIMO) antenna system loaded with metamaterial (MTM) is proposed in this article for fifth-generation (5G) applications. Besides, achievement of duple negative (DNG) characteristics using a proposed compact complementary split-ring resonator (SRR), a broad epsilon negative metamaterial (ENG) with more than 1 GHz bandwidth (BW), and near-zero refractive index (NZRI) features are presented. The proposed mMIMO antenna consists of eight subarrays with three layers that operate in the 5G mind band at 3.5 GHz (3.40–3.65 GHz) with high port isolation between adjacent antenna elements compared to an antenna that does not use MTM. Each subarray has two patches on the top layer, while the middle and bottom layers have two categories of full and partial ground plans, respectively. Simulated, produced, and tested are 32 elements with a total volume of 184 × 340 × 1.575 mm3. The measured findings reveal that the sub-6 antenna has a better than 10 dB reflection coefficient (S11), a lower than 35 dB isolation, and a peak gain of 10.6 dBi for each subarray. Furthermore, the recommended antenna loaded with MTM has demonstrated good MIMO performance with an ECC of less than 0.0001, total efficiencies of more than 90%, more than 300 MHz bandwidth, and an overall gain of 19.5 dBi.
