高数据速率传输、高清流、高速互联网以及无线通信中的诸如超宽带通信系统的基础设施的扩展已经成为在提高服务质量和增加支持千兆比特率的容量时要考虑的需求。大规模多输入多输出（MIMO）系统技术正在从MIMO系统发展并成为第五代（5G）通信系统的高需求并继续进一步扩展。在不久的将来，大规模MIMO系统可能是无线通信系统的主要技术，可以被认为是日常生活中系统的关键技术。在基站（BS）处布置用于上行链路和下行链路的大量天线元件以支持MIMO系统以增加其容量被称为大规模MIMO系统，其指的是在基站处大量提供超过用户设备的单个天线的数量的天线元件。大规模MIMO依赖于空间复用和分集增益，在服务用户与简单的处理信号的上行链路和下行链路在BS。大规模MIMO系统中存在挑战，即使它包含许多数量的天线，诸如信道估计需要是准确的，在BS处的预编码，以及与前两项相关的信号检测。另一方面，在支持宽带蜂窝通信系统和实现低延迟通信和多千兆比特数据速率方面，已经利用了毫米波（mmWave）技术。此外，第五代（5G）新无线电（NR）标准的潜力也受到广泛影响。本研究针对目前大规模多输入多输出天线通信系统的几种设计方法进行了详细的回顾与比较。这些天线有三个局限性被确定用于未来的改进，并提出在设计大规模MIMO天线系统。提出了一些改进弱点和克服挑战的建议，供今后考虑。
High data rate transfers, high-definition streaming, high-speed internet, and the expanding of the infrastructure such as the ultra-broadband communication systems in wireless communication have become a demand to be considered in improving quality of service and increase the capacity supporting gigabytes bitrate. Massive Multiple-Input Multiple-Output (MIMO) systems technology is evolving from MIMO systems and becoming a high demand for fifth-generation (5G) communication systems and keep expanding further. In the near future, massive MIMO systems could be the main wireless systems of communications technology and can be considered as a key technology to the system in daily lives. The arrangement of the huge number of antenna elements at the base station (BS) for uplink and downlink to support the MIMO systems in increasing its capacity is called a Massive MIMO system, which refers to the vast provisioning of antenna elements at base stations over the number of the single antenna of user equipment. Massive MIMO depends on spatial multiplexing and diversity gain in serving users with simple processing signal of uplink and downlink at the BS. There are challenges in massive MIMO system even though it contains numerous number of antennas, such as channel estimation need to be accurate, precoding at the BS, and signal detection which is related to the first two items. On the other hand, in supporting wideband cellular communication systems and enabling low latency communications and multi-gigabit data rates, the Millimeter-wave (mmWave) technology has been utilized. Also, it is widely influenced the potential of the fifth-generation (5G) New Radio (NR) standard. This study was specifically review and compare on a few designs and methodologies on massive MIMO antenna communication systems. There are three limitations of those antennas were identified to be used for future improvement and to be proposed in designing the massive MIMO antenna systems. A few suggestions to improve the weaknesses and to overcome the challenges have been proposed for future considerations.
