Printed eight‐element MIMO system for compact and thin 5G mobile handest

Abstract

A new printed MIMO system with eight elements for a 5G mobile terminal is investigated. The MIMO system consists of printed planar inverted-F antenna elements operating at GSM1900 (1880-1920 MHz), LTE2300 (2300-2400 MHz) and LTE2500 (2540-2620 MHz). The antenna elements have a compact size of 14 mm × 15 mm and are deployed on the non-metalised part of a PCB with dimensions 136 mm × 68.8 mm × 1 mm. By only utilising radiation pattern diversity, good isolations and envelope correlation coefficients for both MIMO systems are achieved. The mean effective gains of the antenna elements are also presented.

Multiple‐input and multiple‐output antenna system with self‐isolated antenna element for fifth‐generation mobile terminals

“…The fifth‐generation (5G) communication technology can provide many advantages such as higher transmission rate and shorter latency over the current 4G system . In order to achieve the higher transmission rate in mobile devices for the 5G bands below 6 GHz, the multiple‐input and multiple‐output (MIMO) system consisting of a relative big number of antennas (eg, 8‐antenna) should be adopted . Due to the limited space in mobile phones, however, how to achieve high isolation for such a big number of antennas becomes a critical challenge.…”

Experimental results of the multi‐Gbps smartphone with 20 multi‐input multi‐output (MIMO) antennas in the 20 × 12 MIMO operation

“…However, owing to the very limited space in the smartphone, it has been a great challenging to embed as many as isolated MIMO antennas therein. Several interesting designs with eight MIMO antennas embedded in the smartphone have been demonstrated recently . The cases with 10 and 16 MIMO antennas to be embedded in the smartphone have also been demonstrated .…”

Dual‐mode and triple‐band 10‐antenna handset array and its multiple‐input multiple‐output performance evaluation in 5G

“…In the last few years, some 5G MIMO arrays operating in sub‐6 GHz have been reported for UE applications . In these papers, exemplary 5G array designs with 10 and 16 isolated antennas, dual‐polarized building blocks and frame antennas have been successfully demonstrated.…”

“…In the last few years, some 5G MIMO arrays operating in sub-6 GHz have been reported for UE applications. [6][7][8][9][10][11][12][13][14] In these papers, exemplary 5G array designs with 10 and 16 isolated antennas, 6,12 dual-polarized building blocks 7,10 and frame antennas 13 have been successfully demonstrated. However, multimode and multiband 5G arrays are seldom reported in these studies.…”
