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.

In this paper, a Multiple-Input-Multiple-Output (MIMO) antenna that can work in Ultra-Wideband (UWB) technology is presented. The antenna can work in frequencies of 3.1-10.6 GHz, has dual bands notched, and in small dimensions at once. The antenna is made in size 34 x 34 x 1.6 mm using a 4-element planar monopole antenna with L-shape and C-shape slits on the radiator. This antenna research was designed and simulated using CST Studio Suite 2019. The design results were fabricated for testing through a Vector Network Analyzer and Anechoic Chamber. The ground plane on the rhombic slot-shaped antenna by utilizing the slot on the antenna radiator produces notched bands from simulations at 3.39-3.64 GHz (WiMAX) and 4.57-5.82 GHz (WLAN). The fabricated antenna has a bandwidth impedance value through S11

A ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna using double Y-shaped decoupling structure with high isolation and triple notched-band is presented. The designed antenna composed of two orthogonally placed monopole elements, coplanar ground and double Y-shaped branch. The defected substrate structure is used to achieve miniaturization. By slotting successively C-shaped slot, semi-circular slot and rectangular slot on the radiation patch and the ground, achieved three notched bands at 3.5 GHz WiMAX, 5.25 GHz WLAN, and 7.5 GHz X-band. The proposed antenna can operate in range of 2.56-12 GHz with triple notched bands of 3.31-3.96 GHz, 4.58-5.67 GHz and 6.57-8.16 GHz. Considering all the results, it can be concluded that the antenna presented has a great performance in terms of good radiation, high isolation (>24 dB), a low level ECC (<0.01) and a high DG level (>9.99), which proves the presented antenna has good prospect in UWB-MIMO systems.
