“…However, based on simulations, the employed feeding technique, which combines the coaxial and coupling feeds, offers a better performance in terms of impedance matching, bandwidth, and isolation. Moreover, since the elements are placed at the corners, the employed feeding technique is more appropriate to reduce the occupied space in the mainboard 31 .…”

This paper introduces a multi-input multiple-output (MIMO) antenna array system that provides improved radiation diversity for multi-standard/multi-mode 5G communications. The introduced MIMO design contains four pairs of miniaturized self-complementary antennas (SCAs) fed by pairs of independently coupled structures which are symmetrically located at the edge corners of the smartphone mainboard with an overall size of 75 × 150 (mm2). Hence, in total, the design incorporates four pairs of horizontally and vertically polarized resonators. The elements have compact profiles and resonate at 3.6 GHz, the main candidate bands of the sub-6 GHz 5G spectrum. In addition, despite the absence of decoupling structures, adjacent elements demonstrate high isolation. To the best of the authors’ knowledge, it is the first type of smartphone antenna design using dual-polarized self-complementary antennas that could possess anti-interference and diversity properties. In addition to exhibiting desirable radiation coverage, the presented smartphone antenna also supports dual polarizations on different sides of the printed circuit board (PCB). It also exhibits good isolation, high-gain patterns, improved radiation coverage, low ECC/TARC, and sufficient channel capacity. The introduced antenna design was manufactured on a standard smartphone board and its main characteristics were experimentally measured. Simulations and measurement results are generally in good agreement with each other. Moreover, the presented antenna system delivers low SAR with adequate efficiency when it comes to the appearance of the user. Hence, the design could be adapted to 5G hand-portable devices. As an additional feature, a new ultra-compact phased array millimeter-wave antenna with super-wide bandwidth and end-fire radiation is being introduced for integration into the MIMO antenna systems. As a result, the proposed antenna system design with improved radiation and multi-standard operation is a good candidate for future multi-mode 5G cellular applications.

“…In addition, the cross-polarizations of the antenna radiation can be deteriorated due to the horizontal surface currents. However, as clearly shown, the antenna provides good cross-polarization radiation patterns with low levels at different frequencies [45][46][47][48]. In the following, the mutual coupling characteristics between the antenna pairs for three different MIMO configurations are investigated.…”

In this research work, a planar crossed exponentially tapered slot antenna with a multiresonance function is introduced. The presented antenna design is ascertained on a low-cost Rogers 5870 dielectric with a circular schematic. The antenna is designed to support several frequency spectrums of the current and future wireless communications. The configuration of the design contains a pair of crossed exponentially tapered slots intersected by a star-shaped slot in the back layer and a bowtieshaped radiation stub with a discrete feeding point extended among the stub parts. The crossed exponential slots exhibit a wide impedance, and the star slot generates an extra resonance at the upper frequencies. For S 11 ≤ −6, the antenna provides a wide operation band of 1.7 to 5.9 GHz supporting several frequency bands of 3G, 4G, and 5G communication. The fundamental characteristics of the proposed slot radiator are studied, and good performances have been achieved.

“…Furthermore, other than these conflicting characteristics, there are other parameters that must be taken into consideration, such as size and volume of the design, which directly affect the manufacturing cost and limits the possible applications that the antenna design can be used due to size weight etc. [10][11][12][13] Thus, design of high-performance horn antenna with the requested performance measures is a challenging problem that requires a complex design process. The implementation of these requirements on a complex design can only be achieved via the use of an accurate Electromagnetic (EM) characterization, for which the usage of full-wave-EM analysis design tools is a must.…”

“…The radiation characteristic of the design can be changed independently than the scattering parameters behavior, whereas in a design with near‐perfect scattering parameter characteristics for the aimed application, the radiation pattern might not be acceptable due to beam dividing or high side lob levels. Furthermore, other than these conflicting characteristics, there are other parameters that must be taken into consideration, such as size and volume of the design, which directly affect the manufacturing cost and limits the possible applications that the antenna design can be used due to size weight etc 10–13 .

Horn antenna designs are favored in many applications where ultra‐wide‐band operation range alongside of a high‐performance radiation pattern characteristics are requested. Scattering‐parameter characteristics of antennas is an important design metric, where inefficiency in the input would drastically lower the realized gain. However, satisfying the requirement for scattering parameters are not enough for having an antenna with high‐performance results, where the radiation characteristic of the design can be changed independently than the scattering parameters behavior. A design might have a high‐efficiency performance, but the radiation characteristics might not be acceptable. Furthermore, there are other design considerations such as size and volume of the design alongside of these conflicting characteristics, which directly affect the manufacturing cost and limits the possible applications. In this work, by using data‐driven surrogate modeling, it is aimed to achieve a computationally efficient design optimization process for horn antennas with high radiation performance alongside of being small in or within the limits of the desired application limits. Here, the geometrical design variables, operation frequency, and radiation direction of the design will be taken as the input, while the realized gain of the design is taken as the output of the surrogate model. Series of powerful and commonly used artificial intelligence algorithms, including Deep Learning had been used to create a data‐driven surrogate model representation for the handled problem, and 80% computational cost reduction had been obtained via proposed approach. As for the verification of the studied optimization problem, an optimally designed antenna is prototyped via the use of three‐dimensional printer and the experimental results ware compared with the results of surrogate model.
