“…Figures 23(c) and 23(d) further present the measured reflection and transmission coefficients, offering valuable experimental insights into the antenna's performance. As shown, the simulation bandwidth is specified as 20 GHz (20-40 GHz), while the measured bandwidth is reported as 15 GHz (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31)(32)(33)(34)(35). The observed shift between the simulated and measured reflection coefficients within the frequency range of 20 to 40 GHz can be primarily attributed to the intricate challenges associated with the fabrication process and the measurement setup, particularly at the mmWave frequencies.…”

“…This alignment is rigorously achieved by adapting the optimization path to adhere closely to the resonant frequency and bandwidth, which are essential measures indicating antenna performance. The selection of the number of RLC circuits to be combined depends on the number of maxima in the real part of the input impedance [32]. As shown in figure 7(c), the real part of the input impedance of the proposed UWB antenna has a single local maximum; therefore, the electrical circuit is designed using one parallel RLC circuit as shown in figure 11(a), while C 0 and L 0 denote the capacitance and the inductance of the antenna at the maxima with the lower frequency [33].…”

The millimeter-wave spectrum has emerged as a compelling solution to address the pressing need for high-dataratecapabilities in the development of 5G technology systems. Spanning between 20 GHz and 40 GHz, this spectrumencompasses several prominent frequency bands crucial for advancing 5G applications. In light of this, our studypresents a thorough investigation into the design and performance of a compact cross-shaped slot broadband antenna,complemented by a 4×4 Multiple-InputMultiple-Output (MIMO) configuration tailored for 5G operations at28 GHz. The primary objective of this study is to develop an antenna system capable of achieving an extended bandwidthranging from 20 GHz to 40 GHz, effectively covering the crucial frequency bands essential for 5G millimeterwave(mmWave) operations. To accomplish this, the optimization of antenna performance is meticulously carried outusing the Radial Basis FunctionNeuralNetworks (RBFNN) model. The RBFNNmodel serves as a robust tool for establishingthe intricate relationship between antenna dimensions, resonant frequency, and bandwidth. Subsequently,the developed RBFNN model is employed to predict optimal antenna dimensions, ensuring resonance at 28 GHz andmeeting specified bandwidth targets. The single antenna is designed with a rectangular patch and a cross-shapedslot and is constructed on the low loss Rogers RT Duroid 5880 substrate. This design reaches an outstanding bandwidthof 19.5 GHz, and exhibits excellent radiation characteristics, with a high radiation efficiency of up to 99% and acorresponding gain of 5.75 dB. The antenna’s design and performance are rigorously designed using HFSS software,which is then compared to the results acquired using CST software. In addition, the proposed MIMO configurationoffers excellent performance in terms of key features such as small size (16 × 16.2 mm2), very wide bandwidth of 20GHz, good gain of 6.75 high isolation exceeding 35 dB, and significant improvements in diversity performance measuressuch as Envelope Correlation Coefficient (ECC), Diversity Gain (DG), Channel Capacity Loss (CCL), Total ActiveReflection Coefficient (TARC), and Mean Effective Gain (MEG). The potential of the proposed MIMO configurationfor high-speed applications is particularly remarkable. Practical verification of the MIMO configuration is carefullycarried out by fabrication andmeasurement. Experimental results strongly confirmthe effectiveness of the proposedantenna design, establishing it as a competitive challenger for 5G technology.

Optimal design of urban cloud transportation planning based on information retrieval and social IoT is proposed in this manuscript. Transportation is a necessary part of the human society's production, life and economic development. With the development of the times and advancement of science and technology, people are strongly dependent on transportation and at the same time, they have put forward more demands on transportation. In this paper, based on the omnidirectional and complex road conditions of vehicle nodes in the urban road network environment, and the road environment has blocking and superimposed interference effects on wireless signals, combined with the intelligent driving model, this paper analyzes and studies the propagation of network worms and builds a stable and reliable system. The experimental results have proven the performance, and the future research directions have been pointed out.
