“…7. Therefore, it can be concluded that the closest distance between antenna elements and the user-head leads to a maximum SAR value, and the furthest distance leads to a minimum SAR value [44,45]. Compared with Figure 8, the maximum reduction of antenna gain is observed for the elements closely spaced with the user's head and hand.…”

A New CPW-Fed Diversity Antenna for MIMO 5G Smartphones

In this study, a new coplanar waveguide (CPW)-fed diversity antenna design is introduced for multiple-input–multiple-output (MIMO) smartphone applications. The diversity antenna is composed of a double-fed CPW-fed antenna with a pair of modified T-ring radiators. The antenna is designed to cover the frequency spectrum of commercial sub-6 GHz 5G communication (3.4–3.8 and 3.8–4.2 GHz). It also provides high isolation, better than −16 dB, without an additional decoupling structure. It offers good potential to be deployed in future smartphones. Therefore, the characteristics and performance of an 8-port 5G smartphone antenna were investigated using four pairs of the proposed diversity antennas. Due to the compact size and also the placement of the elements, the presented CPW-fed smartphone antenna array design occupies a very small part of the smartphone board. Its operation band spans from 3.4 to 4.4 GHz. The simulated results agree well with measured results, and the performance of the smartphone antenna design in the presence of a user is given in this paper as well. The proposed MIMO design provides not only sufficient radiation coverage supporting different sides of the mainboard but also polarization diversity.

“…2 × 2 MIMO systems are successfully employed for 4G mobile networks and the massive MIMO system with a large number of antenna elements is expected to be applied for 5G communications [6][7][8]. Recently, several MIMO antenna designs have been introduced for 5G cellular systems [9][10][11][12][13][14][15]. However, all these mobile-phone antenna designs either exhibit single-band operation frequency or use a few antenna elements with large sizes which could occupy a huge space of smartphone mainboard.…”

A multi-band antenna array is proposed for 5G massive MIMO systems. The presented antenna not only exhibits multi-band operation but also generates the polarization diversity characteristic which makes it suitable for multi-mode operation. Its configuration contains eight modified planar-inverted F antenna (PIFA) elements located at different corners of the smartphone mainboard. For ease integration and design facilitation, the antenna elements and ground plane are etched on the same layer. For S11í10 dB, PIFA elements of the MIMO design operate at the frequency ranges of 2.5-2.7 GHz, 3.4-3.8 GHz, and 5.6-6 GHz covering the LTE 2600, 42/43, and 47 operation bands. Due to the placement of the antenna elements, the proposed design can support both vertical and horizontal polarizations. Fundamental characteristics of the proposed design are investigated. It offers good S-parameters, acceptable isolation, dual-polarized radiation coverage, and sufficient efficiency. In addition, the calculated TARC and ECC results of modified PIFAs are low over the operation bands.

In this paper, an eight-port antenna array operating in the 2.6 GHz band (2550-2650 MHz) for a multi-input multi-output (MIMO) mobile terminal is presented. The configuration of the design is composed of four pairs of low-profile dual-polarized slot antennas that are symmetrically placed at the corners of a mobile-phone mainboard. Each antenna pair consists of miniaturized petal-shaped slot resonators fed by two independent microstrip-feeding lines, thus facilitating radiation pattern and polarization diversity: when acting together, they facilitate multi-channel MIMO operation. The design offers good isolation, dualpolarization and full radiation coverage in a smartphone sized package. A lowcost FR-4 dielectric (ε = 4.4, δ = 0.02, and h = 0.8 mm) with a dimension of 75 × 150 mm 2 is used as the PCB substrate. The characteristics of the smartphone antenna are examined using both simulations and measurements.
