“…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]. Using fractal forms at the nanotechnology level has proven its importance in improving the antenna characteristics in the Terahertz Regime [15].…”

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.

“…In [15], the authors suggested a compact folded patch antenna that operates over an ultra-wide bandwidth. Marzouk et al [16] used an FR4 substrate of size 45 × 42 × 1.6 mm 3 to construct an octagonal UWB fractal antenna. By using an RT5880 substrate and a CPW feed, Niamat et al [17] presented a reconfigurable antenna for UWB operation.…”

The present study proposes a new, highly efficient fractal antenna with ultra-wideband (UWB) characteristics. The proposed patch offers a wide simulated operating band that reaches 8.3 GHz, a simulated gain that varies between 2.47 and 7.73 dB throughout the operating range, and a high simulated efficiency that comes to 98% due to the modifications made to the antenna geometry. The modifications carried out on the antenna are composed of several stages, a circular ring extracted from a circular antenna in which four rings are integrated and, in each ring, four other rings are integrated with a reduction factor of 3/8. To further improve the adaptation of the antenna, a modification of the shape of the ground plane is carried out. In order to test the simulation results, the prototype of the suggested patch was built and tested. The measurement results validate the suggested dual ultra-wideband antenna design approach, which demonstrates good compliance with the simulation. From the measured results, the suggested antenna with a compact volume of 40 × 24.5 × 1.6 mm3 asserts ultra-wideband operation with a measured impedance bandwidth of 7.33 GHz. A high measured efficiency of 92% and a measured gain of 6.52 dB is also achieved. The suggested UWB can effectively cover several wireless applications such as WLAN, WiMAX, and C and X bands.

“…They are commonly used in modern wireless communication systems that require a wide range of frequencies, such as ultra-wideband (UWB) [26][27][28] and wireless local area network (WLAN) applications. In recent times, a few approaches have been reported in the literature to achieve UWB characteristics: tree-like fractal slots [29], compact folded network antennas [30], reconfigurable antennas using diodes on an FR4 substrate [31][32][33], fractal arrays [34], and MIMO (multiple-input multiple-output) antennas [35,36]. The use of reconfigurable components, such as PIN diodes, as in ref.…”

This article introduces a process to design, simulate, and measure a novel multi-band patch antenna with different operation modes, i.e., band centers and bandwidths. Switching between operation modes is possible using a pair of PIN diodes to connect different parts of the antenna with the main antenna patch. Such a reconfigurable design allows for individual control of each frequency range. The main operation mode of the resulting antenna has an impedance bandwidth with two bands, one from 2.4 GHz to 2.73 GHz and another from 3.4 GHz to 5.73 GHz, with a maximum gain of 4.85 dBi and stable radiation patterns. The resulting antenna is suitable for applications using both ultra-wideband technologies and wireless local-area network (WLAN) technologies.
