“…This study will be limited to the study of simple systems, but this approach can be applied without any special changes, including in massive MIMO systems. Many studies investigate other performance factors of MIMO systems such as the bit error rate [14], reliability [16], or design issues [17] and so on.…”

Today, the explosive growth of Multiple Input Multiple Output (MIMO) systems has resulted in a high data rate and consequently permits the operation of a variety of applications. The MIMO networks are multiparameter systems, so the choice of a suitable MIMO network in wireless communications is a complex issue. In this paper, a multi-factoring evaluation and comparison framework was introduced and applied to MIMO systems. The proposed methodology is based on a general distance function, named the General Evaluation Factor. This method was applied to MIMO networks that operate over Rayleigh fading channels with different antenna nodes and spacing. The implementation of this method was based on different capacities and cost values. Nevertheless, while only two factors (capacity and cost) were studied in this paper, the proposed approach was able to incorporate additional performance metrics that might be essential for many wireless system designs. The presented framework and results aspire to be useful for network engineering, especially when finding a balance between contradictory factors (e.g. cost and performance metrics) on MIMO networks.

“…The compact microstrip circularly polarized antenna for 5G wireless communication is in high demand since the advances in semiconductor technology for wireless technology have led to a reduction in cost. Federal Communications Commission (FCC) adopted a new regulation in the 5GHz band, with an additional 400 MHz band, which resulted in a standard IEEE 802.11ac for 5G WLAN application [1]- [3].…”

The research paper presents a novel and compact circularly polarized (CP) antenna for a 5G wireless local area network (WLAN) application. It consists of a circular patch and a coaxial probe feed radiator. Circular polarization (CP) is attained by symmetric semi-circular slits of radius r1 at three edges of a circular path with 90° in direction, and the other semicircular slit is of different radius r2. To improve the impedance bandwidth and axial ratio, the radius of the fourth semicircular slit on circular patch antenna is varied. The design is verified by fabricating a compact antenna of 0.65λ0 × 0.65λ0 × 0.01λ0. The measured 10 dB impedance bandwidth is 3.9 % (5.36–5.56 GHz), 3-dB axial ratio bandwidth is 1.1 % (5.43–5.49 GHz) and gain of 6.6 dBi at resonant frequency of 5.37 GHz is obtained. The authors also describe two-dimensional radiation patterns of azimuth and elevation plane surface current distribution of the CP patch, VSWR < 2. The proposed CP antenna is suitable for the 5G WLAN application. The proposed design is compared with various techniques in literature and tabulated. The measured results are also discussed and they are in good agreement with simulated results.
