“…As shown in Fig. 10, the measured ECC are a litter higher than simulated ones, but both the simulated and measured ECC are lower than 0.1, indicating the better MIMO performance is obtained compared with antenna systems reported in [32,33,34]. The simulated and measured three-dimensional radiation patterns are displayed in Fig.…”

“…Therefore, several multiple-input multiple-output (MIMO) antenna systems for smartphone have been reported in [2,3,4,5,6,7,8,9,10,11]. For instance, a 2 × 2 heptaband antenna system located at the bottom edge of the terminal is demonstrated for WWAN/LTE application [7]. Also, another 2 × 2 WWAN/LTE antenna system operating at the bands of 690 MHz-980 MHz and 1630 MHz-2740 MHz is designed for 5.7-inch mobile handset [8].…”

An 8-port MIMO antenna system covering the band of 3-6 GHz for the 5G MIMO mobile handset applications is proposed. The antenna element consists of an open-slot antenna and a T-shaped feeding strip. Also, an L-shaped strip is adopted to improve the impedance bandwidth and achieve miniaturization simultaneously. The measured results show that wide impedance bandwidth, high isolation (＞ 11 dB), high efficiency (＞ 40%) and lower ECC (＜0.1) are realized. Finally, the hand-grip effects are investigated by simulation to verify its capability for the industrial applications.

“…In [8], a novel PIFA antenna with a slot is proposed, in order to add a new resonant frequency. Moreover, others used a hybrid of a Franklin strip monopole antenna and a rectangular patch antenna [9], the design of a dual feature of the rectangular open-ended ground slot is proposed in [10], and the structure of an outstanding ground to decouple is used in [11][12][13]. Four conductive, innovatively designed antenna elements are diagonally placed on the flexible polyamide substrate, which could keep operating when the antenna is bent in [14].…”

In this article, a miniaturized antenna is proposed for 4G/5G multiple input, multiple output (MIMO) applications for smartphones. The proposed antenna is composed of an inverted L-shaped antenna with decoupled elements to cover 4G (2000–2600 MHz), and a planar inverted-F antenna (PIFA) with a J-slot to cover 5G (3400–3600 MHz and 4800–5000 MHz). Furthermore, to achieve the purposes of miniaturization and decoupling, the structure adopts a feeding stub, shorting stub, and outstanding floor, additionally adding the slot to the PIFA, to generate additional frequency bands. Due to the advantages such as multiband operation, MIMO configuration for 5G communications, high isolation, and a compact structure, the proposed antenna design is attractive for 4G/5G smartphones. The antenna array is printed on an FR4 dielectric board, measuring 140 × 70 × 0.8 mm3, with the 4G antenna located on a top 15 mm-long headroom.

This paper presents the design of a multiple-input and multiple-output (MIMO) antenna for a fifth-generation (5G) smartphone that will work in dual-band. The antenna proposed in this work operates at 2 frequency ranges, i.e., (3300-3600) MHz and (4800-5000) MHz. The antenna design consists of four antennas that are placed perpendicular to the edge of the system and this makes it different from the traditional 5G antennas. The area of each antenna on the side frames is (3.9×17 mm), and hence can be used in ultra-thin smartphones for 5G applications. The reflection coefficient obtained in the simulations is less than -6 dB for the required band, which suggests that the required impedance matching is obtained. The antenna proposed is designed by using central time zone (CST) microwave studio.
