“…The proposed antenna in [24] operates only in LTE band 42 and 43 and has a impedance bandwidth of only 11.11 %. In [25], [26] 4 × 4 MIMO antenna array is designed that will have lesser peak channel capacity values when compared to the proposed antenna. In [27], [28] edge side-frames with thickness upto 7 mm are used to design the antenna elements.…”

A 10 element multiple input multi output (MIMO)/Diversity antenna system is considered to work in Sub-6 GHz frequency range. The proposed design can work in long term evolution (LTE) band 42(3.4-3.6 GHz), LTE band 43(3.6-3.8 GHz) and LTE band 46(5.15-5.925 GHz). The proposed design consists of 10 identical and highly isolated T-shaped slot antennas fed with T-shaped lines. All three bands have the return loss values (<-6 dB) and total antenna efficiency (>83%) in free space. The peak value of envelope correlation coefficient is 0.06 and the calculated value of ergodic channel capacity is found to be greater than 41bps/Hz in all the bands.The effect of hand grip as well as the presence of battery and LCD screen is investigated. Simulated results are validated via fabrication and measurement of the proposed design.

“…Another point of this proposal is the authors have not done any SAR analysis which is very important for the implementation of this design in the smartphone. A quad port 2 × 2 MIMO antenna for smartphones has been proposed in [7]. The single antenna element for the MIMO is based on the combination of L-shaped, rectangular shaped and Z-shaped strips.…”

Here, a planar 2×2 MIMO configuration for the 5G smartphone has been presented. A single element modified planar tree profile shape (MPTPS) antenna is implemented to investigate the suitability in future 5G communication for different sub-6 GHz spectrum band. The size of the single MPTPS antenna is 40 × 25 mm 2 . The electronic band gap (EBG) and partial ground plane (PGP) techniques have been utilized to tune this antenna. The antenna works from 2.81 -7.23 GHz, with a (VSWR < 2) bandwidth of 4.42 GHz that covers all the midrange sub-6 GHz 5G frequencies. It also has a comparatively good gain of 3.14 dBi, high efficiency of 96% and a bi-directional radiation pattern. The antenna has been implemented in a 145 × 75 mm 2 smartphone mainboard with MIMO configuration using polarization diversity. More than -21.1 dB isolation has been found between different ports. A good gain of as high as 6.59 dBi is observed for the MIMO in the band. Also, as MIMO performance, excellent envelope correlation coefficient of less than 0.0029 and minimum diversity gain of 9.9853 has been observed. The investigation has been further stretched by adding a liquid crystal display (LCD) for radiation performance and a hand phantom to assess the performance in terms of specific absorption rate (SAR). It is observed that the SAR value is as low as 0.887641 at 3.5 GHz. This design will motivate the researcher to develop high performance MIMO arrays for 5G smartphones.

“…In [22], an eight element MIMO antenna system is proposed for sub-6 GHz 5G mobile terminals. The proposed antenna array in [23] consists of an L-shaped feeding strip, a parasitic rectangle strip, and a modified Z-shaped radiating strip, which operates on the 3.5 GHz band (3.4-3.6 GHz) and 5 GHz band (4.8-5 GHz) for the applications of 5G. A multi-band MIMO antenna is designed to meet the requirements of the 4G and 5G mobile terminals with essential bandwidth for higher data rate applications [24].…”

In this paper, a compact planar dual-band multiple-input and multiple-output (MIMO) antenna with high isolation is presented to satisfy the increasing requirements of wireless communication. The proposed antenna array consists of two identical radiating elements which are fed through micro-strip lines. A rectangular micro-strip stub with defected ground plane is employed to achieve a high isolation which is less than −15 dB between the two antenna elements. The size of the entire MIMO antenna is 32 × 32 × 1.59 mm3, which is printed on an FR4 substrate. The proposed MIMO antenna is optimized to operate in 2.36–2.59 GHz and 3.17–3.77 GHz bands, which can cover the fifth-generation (5G) n7 (2.5–2.57 GHz) and the fourth-generation (4G) Long Term Evolution (LTE) band 42 (3.4–3.6 GHz). The proposed MIMO antenna is feasible for the 5G and 4G applications.
