“…ECC represents the correlation between the received signals of two antennas. It is a critical indicator to evaluate the diversity performance of a multi-antenna system, and it can be obtained from Equation 1as [11], where q * sml represents the conjugate complex of q sml , and q sml is the complex coefficient of the spherical harmonic. The parameter of m describes the azimuthal variation of the field.…”

An eight-element ultra-wideband multiple-input multiple-output antenna system is proposed for the 5G mobile terminals. Each radiating branch is composed of a Loop and a monopole antenna. The ultra-wideband characteristics of the antenna are obtained by a T-shaped feed branch coupling a radiation branch. Furthermore, the isolation is lower than −15 dB by introducing a Tshaped neutralization line structure. The results of simulation and measurement show that the antenna system can cover 3.3-5.6 GHz, and the antenna efficiency is 45%-80%. At the same time, the envelope correlation coefficient between any two elements is lower than 0.03. Therefore, the proposed antenna in this study is very suitable for the eight-element MIMO antenna system as a reference.

“…4 presents an exploded view drawing of the proposed antenna. The antenna element shares similar features and working principles of our work proposed in [17] However, a major difference between the two antennas is that the proposed antenna element in this paper uses a transparent radiating layer.…”

“…Note that, due to the random orientation of the user, the polarization of the mmWave handset array is also random. To reduce the probability of polarization mismatch between the base station and the user, ±45 • tilted array elements are employed at the base station in practice [28]. This base station antenna configuration is assumed for simulations in the next section.…”

The fifth generation (5G) millimeter-wave (mmWave) handset demands a cost-effective mmWave array antenna with beam steering capability to overcome the high-pass loss and to ensure seamless connectivity. Unlike sub-6-GHz handsets, emerging mmWave handsets usually employ phased array antennas with a reasonably large number of elements. Unfortunately, due to the legacy of a few antennas in sub-6-GHz handsets, the mutual coupling effect on the mmWave handset has not been thoroughly investigated. In this paper, we study the mutual coupling effect on the mmWave handset performance by comparing array antennas with different inter-element spacing and different configurations. It is found that mutual coupling tends to increase the active reflection (especially at large scanning angles), which in turn reduces the realized gain and maximum scanning angle of the phased array antenna. For a sub-6-GHz multiple-input multiple-output handset with two or four antenna ports and fully digital precoding/decoding, 10-dB isolation is usually regarded as good enough. It is shown in this paper, however, that the outage capacity of the mmWave handset can be clearly improved by reducing the mutual coupling.
