“…Figure 2 presents (a) a traditional circular patch antenna resonating at 10.8 GHz (30 mm in diameter) and (b) a traditional circular patch antenna with an additional SRR structure, which were modelled and simulated using the High Frequency Structural Simulation software tool (HFSS) (ANSYS Inc., Canonsburg, PA, USA) [18]. SRR structures offer an improved performance compared to traditionally designed microstrip patch antennas as they allow for miniaturised antenna dimensions and/or multiband operations, i.e., multiple resonant frequencies [19]. In this study, the SRR structure was used to provide multiple resonant frequencies between 1 to 10 GHz, which provided more details about the concrete.…”

This paper investigates the possibility of applying novel microwave sensors for crack detection in reinforced concrete structures. Initially, a microstrip patch antenna with a split ring resonator (SRR) structure was designed, simulated and fabricated. To evaluate the sensor’s performance, a series of structural tests were carried out and the sensor responses were monitored. Four reinforced concrete (RC) beam specimens, designed according to the European Standards, were tested under three-point bending. The load was applied incrementally to the beams and the static responses were monitored via the use of a load cell, displacement transducers and crack width gauges (Demec studs). In parallel, signal readings from the microwave sensors, which were employed prior to the casting of the concrete and located along the neutral axis at the mid-span of the beam, were recorded at various load increments. The microwave measurements were analysed and compared with those from crack width gauges. A strong linear relationship between the crack propagation and the electromagnetic signal across the full captured spectrum was found, demonstrating the technique’s capability and its potential for further research, offering a reliable, low-cost option for structural health monitoring (SHM).

“…Famous mathematicians such as W. Sierpinsky, N. Von Koch, D. Hilbert and H. Minkowski have significantly contributed to fractal geometry [1]. Their fractal concepts inspired the resonator engineering community to explore the potential use of these geometries in antenna research and design in Ghz regime to minimize the size of the antennas which has a high radiation efficiency, they are considered the fractal geometry in the manufacturing of the antennas [2][3][4]. In references [5][6][7][8][9][10], fractal forms were utilized to enhance antenna characteristics, whereas a combination of metamaterials and fractal shapes was employed to improve properties in references [11][12][13][14].…”

This study presents a new approach for characterizing the 3D printing electromagnetic properties in Polylactic Acid (PLA) using a novel cross-fractal sensor. The CST Studio Suite simulation, employing the finite element method (FEM), and the ADS simulation software, based on the equivalent circuit of this novel sensor, are utilized to enhance confidence in the convergence of simulation and measurement results. The analysis confirms that the real sensor, based on a cross-sectional fractal resonator, exhibits excellent sensitivity, selectivity, and linearity. Sensor performance is evaluated through two methods: the frequency-based approach and the S11 parameter analysis. In the frequency-based method, the sensor demonstrates a typical sensitivity of 0.0302 GHz/cm³, while in the S11 parameter analysis, it exhibits a typical sensitivity of 0.3065 dB/cm³. These results underscore the high sensitivity and linearity of this innovative sensor. The using of this novel cross fractal sensor, it promises to show how to properly adjust 3D printer parameters, potentially setting the "infill percentage" of the 3D print, this is because the proportion of air present changes when the printing percentage is changed, which can lead to (εr) and loss-tangent (tan (δ)) with varying the infill percentage, by the resonance frequency (fr) approach demonstrates a characteristic sensitivity of 0.1822 GHz/RIU. The experimental study confirmed that the fabricated sensor exhibits miniaturization (with an electrical size of λ0/8), high sensitivity, and excellent linearity in the frequency approach, with a typical sensitivity of 0.004615 GHz/%. The suggested biosensor demonstrated its capability to detect low concentrations of ethanol. These aqueous solutions, containing known alcohols like ethanol in low concentrations, enables identification of Halal and alcohol-free products in food sensing applications.

This study proposes an E-shaped microstrip patch antenna array (MSPAA). The substrate is RT/Duroid5880. Its 2.2 dielectric constant gives it a larger bandwidth than substrate materials with higher dielectric constants. The periphery dimension of a single E patch is 50 × 41 mm2. The areas of 2 × 2 and 3 × 3 MSPAAs are 120 × 96 and 180 × 144 mm2, respectively. Array members are 10 and 7 mm apart horizontally and vertically, respectively. MTM technology builds the projected MSPAA. This work looks at the effects of gain, reflection coefficient (return loss), directivity, bandwidth, and VSWR on proposed 2 × 2 and 3 × 3 MSPAAs with different patch lengths of 30, 40, and 60 mm, patch widths of 40, 50, and 60 mm, and substrate thicknesses of 0.8 and 1.6 mm. Also, this study compares the performance of existing E-shaped MSPAAs with proposed 2 × 2 and 3 × 3 MSPAAs. The suggested MSPAA performs better than the existing E-shaped MSPAA. The series network analyzer measures the prototype MSPAA’s experimental outcomes. The polynomial is recommended for estimating the antenna array area with odd and even rows and columns. CST Studio Suite software analyzes and designs antenna arrays, and simulation findings are compared with hardware results. The main benefit of the proposed 2 × 2 MSPAA is that it reduces sidelobes. It has a gain of 8.9 dBi, a directivity of 8.95 dBi, a VSWR of 1.02, a return loss of −32.91 dB, and a bandwidth of 0.1 GHz at both 1.6 and 0.8 mm substrate material thicknesses. Across its operating range of 3.8–4.2 GHz, the recommended array antenna has a radiation gain of 7.01–7.81 dB and an efficiency of 68.51–71.11%. At 4 GHz, this study looks at how electronic steering affects the phase angle of the excitation signal, the number of elements, and the distance between elements in the beam steering linear phased antenna array (BSLPAA) using MATLAB.
