“…In MIMO wireless systems, multiple antenna elements are adopted to work as transmitter and receiver, improving the data transmission rates of high-resolution images from the capsule to outside base station/gateway over single antenna topology in multipath channels [31]. Recently, planar monopole antennas with a pair of elements were proposed, verifying that antennas operate at ISM 2.4 GHz along with MIMO technique that can be applied for wireless devices, realizing high data rate in limited range and space [32][33][34][35][36][37][38].…”

A compact four-element multiple-input multiple output (MIMO) antenna is proposed for medical applications operating at a 2.4 GHz ISM band. The proposed MIMO design occupies an overall volume of 26 mm × 26 mm × 0.8 mm. This antenna exhibits a good impedance matching at the operating frequency of the ISM band, whose performance attributes include: isolation around 25 dB, envelope correlation coefficient (ECC) less than 0.02, average channel capacity loss (CCL) less than 0.3 bits/s/Hz and diversity gain (DG) of around 10 dB. The average peak realized gain of the four-element MIMO antenna is 2.4 dBi with more than 77 % radiation efficiency at the frequency of interest (ISM 2.4 GHz). The compact volume and adequate bandwidth, as well as the good achieved gain, make this antenna a strong candidate for bio-medical wearable applications.

“…In fact, the main difficulty in designing compact MIMO antennas is to achieve high levels of isolation between adjacent antennas while maintaining excellent radiation efficiency. In this area, several useful solutions to get proper isolation levels and compact MIMO structures are reported . In, the miniaturization technique is introduced to achieve good isolation, for two‐coupling element antennas designed for MIMO‐4G systems.…”

“…Similarly, the miniaturization technique has been proposed in Reference , by using the meandered feeding lines, to achieve a 2‐port MIMO system.

Here, an ultra‐compact Multi‐Input‐Multi‐Output (MIMO) antenna system is presented for Wireless Local Area Network (WLAN) applications. The proposed antenna compactness approach is based on using Cylindrical‐Dielectric‐Resonator‐Antenna (CDRA) symmetry with the help of image theory to achieve the best size reduction of the resonators and maintain the resonance frequency of the original CDRA. The electric/magnetic walls approach is utilized to miniaturize the size by exploring the symmetry and antisymmetry of the resonant mode. First, a CDRA for MIMO system is designed and tested in terms of return loss and radiation efficiency. Then, two configurations of MIMO‐Antennas (two and four ports) are examined by using the same substrate size. The 2‐port‐MIMO antenna is built from two half‐CDRs (HCDRs) facing each other. Similarly, four‐quarter‐CDRs (QCDRs) are created to form a 4‐port MIMO antenna system. As a result, a 75% size reduction is achieved (size of 30 × 30 × 7.62 mm3). The measured impedance bandwidth for the 4‐port MIMO antenna is 5.4% (5.4‐5.7 GHz), with more than 15 dB isolation levels. Proper levels of Envelope Correlation Coefficients (ECCs) are also achieved (1 × 10−2‐4 × 10−2), with a channel capacity loss (CCL) of 0.04 bits/S/Hz. The proposed MIMO antennas are suitable for compact wireless communication systems.

A novel high performance four-port multiple input multiple output antenna is suggested for 5G application functioning at 3.4 GHz band. The antenna design measures an inclusive volume of 32 mm × 32 mm × 0.8 mm 3 . The broad frequency bandwidth, excellent gain, decreased interelement gap, and effective isolation within the MIMO components of the proposed system are clearly novel. Each antenna in the four-element MIMO system has been situated orthogonally to the others while maintaining a small size and good result. The antenna has exceptional average total efficiency in the 5G sub-6 GHz spectrum and is in good agreement with the measured results. It also offers a high realized gain compared to prior MIMO antennas. The antenna has a high impedance matching whose isolation is about −28 dB, computed envelope correlation coefficient smaller than 0.10, channel capacity loss average value less than 0.2 bits per second per hertz, and the diversity gain about 10 dB. The typical peak realized antenna gain of the offered MIMO antenna is also delivered with a high radiation efficiency at the frequency of 3.4 GHz. The reflection coefficient, mutual coupling, radiation pattern, current distribution, and gain of antennas are all measured and explained. The design has a compact high volume and adequate bandwidth with good accomplished gain making the antenna very strong for 5G application.
