MIMO Antenna System for Modern 5G Handheld Devices with Healthcare and High Rate Delivery

Abstract

In this work, a new prototype of the eight-element MIMO antenna system for 5G communications, internet of things, and networks has been proposed. This system is based on an H-shaped monopole antenna system that offers 200 MHz bandwidth ranges between 3.4–3.6 GHz, and the isolation between any two elements is well below −12 dB without using any decoupling structure. The proposed system is designed on a commercially available 0.8 mm-thick FR4 substrate. One side of the chassis is used to place the radiating elements, while the copper from the other side is being removed to avoid short-circuiting with other components and devices. This also enables space for other systems, sub-systems, and components. A prototype is fabricated and excellent agreement is observed between the experimental and the computed results. It was found that ECC is 0.2 for any two radiating elements which is consistent with the desirable standards, and channel capacity is 38 bps/Hz which is 2.9 times higher than 4 × 4 MIMO configuration. In addition, single hand mode and dual hand mode analysis are conducted to understand the operation of the system under such operations and to identify losses and/or changes in the key performance parameters. Based on the results, the proposed antenna system will find its applications in modern 5G handheld devices and internet of things with healthcare and high rate delivery. Besides that, its design simplicity will make it applicable for mass production to be used in industrial demands.

Multiple Elements MIMO Antenna System With Broadband Operation for 5th Generation Smart Phones

“…Therefore, to address such challenges, it is believed that Multiple-Input-Multiple-Output (MIMO) technology can be a better solution to achieve a high data rate requirement by reducing the processing time of data and to improve the transmission rate [5]. Moreover, two portions of the spectrum i.e., Sub-6 GHz and millimeter wave portion of the spectrum are also being considered to upgrade the current technology [6][7][8]. From literature, it is evident that sub 6 GHz band is quite matured in terms of experiments and research conducted [9].…”

Mutual Coupling Reduction through Defected Ground Structure in Circularly Polarized, Dielectric Resonator-Based MIMO Antennas for Sub-6 GHz 5G Applications

“…Because of the absence of side waves, as well as elevated radiation effectiveness, extreme gain, adjustable structure, and exciting mechanisms, dielectric resonators have become a viable alternative for MIMO antennas in recent years [ 1 ]. Only a limited investigation articles on MIMO DRA are available in the open literature [ 2 , 3 , 4 , 5 , 6 ]. A rectangular MIMO DRA for 4G applications has been proposed in ref.…”

“…MIMO antenna based on DRA for radio access points has been offered in ref. [ 5 ]. The desired MIMO antenna can shelter the 2.45 and 5.8 GHz WLAN/5G NR groups with just one group of large and small DRAs.…”
