“…All the results are tabulated in Table II For the antenna performance comparisons, the specific antenna parameters (i.e., ( , and G) together with the % ESR and % PSR values are listed in Table III, if exists, regarding the proposed Antenna C together with the other single microstrip antennas reported in literature whose DGS are composed of CSRRs. Herein multiple input multiple output (MIMO) antenna designs [22,44,53] are not included in the comparison table since the usage of multiple antennas in the design may affect the individual antenna performances and this may cause an unfair comparison. In addition, the CSRR based DGS structures reported in reference [48] are also not included in the comparison table since the study mainly focuses on the sensor application rather than designing a small antenna thus the fundamental antenna parameters such as gain, efficiency and radiation pattern are not provided.…”

In this study the effects of using defected ground structures (DGS) composed of a complementary split ring resonator (CSRR) and CSRR with dumbbell (CSRR-D) for rectangular microstrip antennas are investigated. On this aim, two different antennas, which are Antenna B having CSRR etched DGS and Antenna C having CSRR-D etched DGS are designed and fabricated in comparison with the ordinary rectangular patch antenna, which is Antenna A. In both Antennas B and C, CSRR structures are etched in the same position of the ground planes. On the other hand, another ordinary microstrip antenna, called Antenna D, is designed at resonance frequency of Antenna C. For the characterization; resonance frequencies, voltage standing wave ratios, percentage bandwidths, gains, ka values and gain radiation patterns are investigated both in simulations and experiments. The numerical analyses show that 29.39% and 44.49% electrical size reduction (ESR) ratios are obtained for Antenna B and Antenna C, respectively in comparison to Antenna A. The experimental results verify the ESR ratios with 29.15% and 44.94%. Supporting, Antenna C promises 68.12% physical size reduction (PSR) as it is compared with Antenna D. These results reveal that Antenna C is a good alternative for DGS based microstrip electrically small antennas.

“…Multiple antenna elements are arranged in a specific pattern with a phased array configuration. Phased array systems allow for beamforming, where the antenna elements are individually controlled to steer the radiation pattern toward the desired direction, thereby achieving gain [91]. The gain of 6.7 dBi is enhanced to 12.8 dBi by comprising four elements in each array [79].…”

A comprehensive review of multiband MIMO antennas designed for wireless applications in the 5th and 6th generation (5G and 6G) networks is presented. The demand for higher data rates and improved spectral efficiency in advanced wireless networks continues growing, and multiband MIMO antenna systems have emerged as a promising solution. This review aims to provide an indepth analysis of the existing literature on multiband MIMO antennas for 5G and 6G wireless applications. The paper's main objectives are: (1) To emphasize the requisite of MIMO antenna for the sub-6 GHz of 5G/6G wireless communication, (2) To demonstrate various techniques to generate multi-band, (3) To highlight the challenges and their potential solutions to design multiband MIMO for 5G/6G, (4) To investigate the methods to attain circular polarization (CP) and pattern diversity for better system performance. The review critically analyzes the latest advancements, challenges, and future research directions for multiband MIMO antennas in the context of 5G and 6G wireless networks. This comprehensive review serves as a valuable resource for researchers, engineers, and practitioners seeking a deeper understanding of multiband MIMO antennas and their potential to support the demands of the ever-evolving wireless communication technology.

“…As the maximum isolation between the middle and the top antenna element is 10 dB, this results in limited practical application. In summary, the antenna system discussed mainly focused on the GSM/UMTS frequency band of operation in low radio frequency bands [3][4][5][6][7][8][10][11][12][13][14]. Moreover, accommodating multiple antennas at the low-frequency band is a daunting task on a limited footprint area of a smartphone due to the transfer of power among ports.…”

In this paper, the systematic design of a multiple antenna system for 5G smartphone operating at 3.5 GHz for multiple-input multiple-output (MIMO) operation in smartphones is proposed. The smartphone is preferred to be lightweight, thin, and attractive, and as a result metal casings have become popular. Using conventional antennas, such as a patch antenna, Inverted-F antennas, or monopole, in proximity to metal casing leads to decreasing its total efficiency and bandwidth. Therefore, a slot antenna embedded in the metal casing can be helpful, with good performance regarding bandwidth and total efficiency. The proposed multiple antenna system adopted the unit open-end slot antenna fed by Inverted-L microstrip with tuning stub. The measured S-parameters results agree fairly with the numerical results. It attains 200 MHz bandwidth at 3.5 GHz with ports isolation of (≤−13 dB) for any two antennas of the system. The influence of the customer’s hand for the proposed multiple antenna system is also considered, and the MIMO channel capacity is computed. The maximum achievable MIMO channel capacity based on the measured result is 31.25 bps/Hz and is about 2.7 times of 2 × 2 MIMO operation.
